The core content of "Mathematical and Physical Separation Characteristics in Finite Element Method" and "Influence Domain of Mathematical Crack Tip" are all about the strengthening and improvement of cohesive crack propagation, mainly for the research of cracks in various materials under special environments.As an engineering student, Wei Shuxun can still understand a little bit, but he can’t understand it if it’s too detailed. Similar experiments with discrete radiation were carried out during optical experiments, but the results were completely opposite.Sure enough, it is because of different usage, so the effect is different, try it next time... Stop, think too much!

Wei Shuxun rubbed his hair vigorously. He just planned to fill out a "Double Degree Application Form". After passing the double degree first, let's talk about experiments, etc., after graduation—if he can be admitted to a graduate student.

"Learning machine, give me relevant information on cohesion crack research for the past five years."

"Di—data extraction." In front of Wei Shuxun, several columns of new research materials on cohesion cracks popped up. In 5 years, there has been no major breakthrough in the data on cohesive cracks, but there are some more flexible changes than now.Wei Shuxun didn't intend to go too far, so he extracted a paper and spent three days studying it carefully. Of course, during this period, he went to the library to check the information, mainly because the learning machine refused to be a dictionary. Many professional terms Wei Shuxun I don’t understand, such as the area of ​​influence of the tip of a mathematical crack, radial ribs, fracture instability, etc., I know every word, and when put together, I can’t even do it.

The students in the class are used to Wei Shuxun going to the library at the beginning of each semester, and no one bothers him. Sometimes the dormitory people see him fascinated by reading, and help him to bring home meals.After three days to get an idea, Wei Shuxun studied for two more days. Before the deadline for double degree application, Wei Shuxun finally filled out the "Dual Degree Application Form" and handed it in to the Office of Academic Affairs.

Yu Xin also applied for a double degree, so he paid close attention to Wei Shuxun. After he handed in the application form and came back, he immediately asked, "Shuxun, which school did you apply for as a major?"

Wei Shuxun has a make-up exam record, so he can only apply to other schools. Some schools with less strict requirements don’t care about the make-up exam record. Of course, the degree of these schools is not very prestigious, but it is a certificate, which can facilitate future job hunting .

Wei Shuxun couldn't explain too much, just nodded with a smile: "I have already applied for Engineering Mechanics at University A."

"Hey? But what about your make-up exam records?"

Wei Shuxun shrugged: "Give it a try, if it doesn't work, I'll apply to other schools."

With so many students in the school, the Academic Affairs Office naturally didn't have time to review them one by one. They just sorted the students' applications by major and handed them over to the teaching assistants of the professors of each major, who then conducted a preliminary review.Because I am a student of this school, basically as long as the credits are up to the standard and there is no make-up exam record, I can pass the application.

There are records in the school database in this regard. One teacher is responsible for reading the student number, and one teacher checks. If there is no problem, it is passed. It is simple and fast, and nearly a hundred copies can be reviewed in one day.

"No. B2-036." Assistant Professor Lin read the student number, and Assistant Professor Li next to him typed on the computer, and answered after a while: "Passed."

Assistant Professor Lin put the materials into the qualified file basket.

The two of them were in charge of the application for the major of Engineering Mechanics. There were not many applications for this school alone, but as an excellent major of University A, there were still many applications from students from other schools, so there were quite a few applications to be reviewed.Of course, the applications from other schools were temporarily put aside, and the two gave priority to reviewing the applications of students from this school.

Basically, there are no problems. Occasionally, I can see the application forms of students who do not have enough credits or have re-examination records. No one dares to lie about their grades, but they will write how much they love engineering mechanics on the application form. This major, the professors of engineering mechanics are so excellent, I ask the school to give me a chance.

Assistant Professor Lin was delighted to see the flattering sentences of these students, but still put their application forms in the unqualified document basket without compassion.

"No. A3-015."

I took another application form, read out the student number habitually, and scanned down, only to find that "there is a make-up exam record" has been written on the application description in the second column, which obviously cannot pass.

"No need to check..."

"There is a make-up exam record."

As soon as he said that there is no need to check, Assistant Professor Li has already found out his information. Assistant Professor Lin was about to put this application form in the unqualified document basket, when his eyes suddenly swept to the "reason for applying for study" in the third column. What a student wrote seems to be not how much he likes engineering mechanics. The first sentence is "I found that the fracture instability process is related to the strength of the radial rib short shell. The WUME algorithm is introduced to classify the radial rib short shell, and the F mesh enters the adaptive mode. , the cohesion crack tightening force is enhanced."

"Huh? What is this?"

Assistant Professor Lin took it over and read it carefully. The student did not write much, but briefly described his discovery in the laboratory that the tightening force of cohesive cracks can be enhanced by grading short shells with radial ribs.Then the student said that it was just an accidental discovery, and he didn't quite understand its principle and function. A student, this student is very interested in these phenomena, and hopes to conduct more in-depth study and more systematic research, instead of wasting time on the road to and from other schools, and asks the school to approve the double degree study in school.

The last few words were not very polite, and in the eyes of Assistant Professor Lin, he was even arrogant, but as a person who had studied the expansion of cohesion cracks, he was more concerned about the other contents of this student.Although there were only a few short sentences, it made him see another research direction.Assistant Professor Lin couldn't help standing up, walked out of the office with the application form, and Assistant Professor Li next to him asked suspiciously, "Assistant Lin, where are you going?"

"I have something to do, please wait a moment." After speaking, he hurried to the laboratory to conduct experiments.There are only a few words on the application form about the findings during the experiment, without any detailed values ​​or explanations, but for Professor Lin, a few words are enough for his own analysis, and he does not plan to conduct experiments at this time, just a little test To confirm the feasibility of the experiment.

It is successful, the experiment is feasible, and although there is not much improvement on the current cohesion crack, it also provides a new research direction.Most importantly, he can write a paper again!

To be promoted from a teaching assistant to a lecturer, in addition to the number of years, University A also requires to publish more than 2-3 papers in core journals every year. Being able to write one more paper is really important for teaching assistant Lin.

Excitedly looking at this application form again, I found that the student's name is Wei Shuxun, a student of "Electronic Science and Technology".This student suggested an idea for him, reciprocate, and he should also help this unqualified outstanding student.

"Professor Zhong, there is a student's application form, I would like you to take a look at it." Assistant Professor Lin found Professor Zhong and wanted to show him Wei Shuxun's application form.

"What's the problem?" Professor Zhong asked directly, writing something without looking up.

"Uh, his make-up exam record."

"That's unqualified."

"But he is very good, and he can conduct experiments by himself only in his sophomore year." Assistant Professor Lin said hastily: "And he unexpectedly discovered another strengthening direction for the expansion of cohesion cracks."

"What?" Professor Zhong finally looked up with interest.

"Please take a look." Assistant Professor Lin handed Wei Shuxun's application form to Professor Zhong: "He seems to have discovered it by accident. I probably don't know what this experiment does, but I think he can be created. materials, strong hands-on ability, there are not many students who can carry out experiments in their sophomore year, and even fewer students can improve the cohesion crack growth."

Professor Zhong looked at Wei Shuxun's application form, and was surprised: "Huh? It turns out that the expansion of cohesive cracks can also enter self-adaptation through graded radial ribs? I never thought about it."

"Right? This student has great potential."

"Well." Professor Zhong nodded. This discovery is not a big deal to the knowledgeable Professor Zhong. He is more interested in what Wei Shuxun said later. As a pure researcher, he hates wasting time, especially It is also a waste to waste time on the road, and let a potential student spend time on the way to and from school.

"It's too wasteful to let him go to another school, and it's a waste of study time." Professor Zhong took the pen, wrote his approval on Wei Shuxun's application form, and handed it back to Assistant Professor Lin: "That's it, let him Double major at University A."
