Professor Yang naturally didn't know all kinds of Mu Jingchi in his heart.

For him, there is a systematic existence that can learn future material knowledge, so he must make good use of this knowledge and contribute to himself, the country, and society.

Maybe there are difficulties, maybe a certain project can be stuck for a few years, but Mu Jingchi is not afraid.

"By the way, there is one more thing, the School of Materials asked you if you have any ideas for a position. ”

Professor Yang Wenwu took the topic to the other side, and Mu Jingchi's topic did not continue to flip, he planned to leave enough time to read it carefully, not now.

"I'm not capable enough!"

Mu Jingchi's first thought was about his own ability, scientific research ability is one thing, but teaching is another. The former is a matter of knowledge practice, while the latter is a matter of education.

A good learner, a researcher, is not necessarily a good educator. Although judging from the three material papers, Mu Jingchi's knowledge system is deep enough to have the strength to disseminate knowledge.

"You can consider starting as a teaching assistant and moving up to a lecturer when you get used to the teaching model. ”

Yang Wenwu obviously has a tendency towards Mu Jingchi, hoping that he will stay in the school, "And this will not affect your scientific research projects, sometimes simply giving lectures to spread knowledge can provide you with inspiration, and can also be used as a way to relax." ”

Mu Jingchi agrees with Professor Yang's view, but he has a better choice!

The study enveloped by the Super Happy Family Home system provides inspiration, while the living room and bedroom are better options for him to relax.

Being a teacher?

Perhaps everyone has the characteristic of being a good teacher, because this is the act of putting one's own thoughts into other people's heads.

Besides, if you want to change the country's material problem, if he is the only one, the pressure is too great. If we disseminate our future knowledge through education, we will cultivate more material talents.

Even if he can't help Mu Jingchi in the general direction, at least he has more helpers and can keep up with his material ideas.

Mu Jingchi was a little moved.

"Still, Professor. ”

Mu Jingchi also has his own concerns, "I still want to engage in composite materials in the future, mainly in national defense and military." If I work at Huaqing University, then it will be difficult to enter the National Defense Military Industry Research Institute, right?"

There is another meaning in this remark, Huaqing University is a university after all, and compared with the National Defense and Military Industry Research Institute, the nature of secrecy is different after all.

"What did I think you were worried about?"

Yang Wenwu waved his hand, not taking Mu Jingchi's worries to heart, "I know what you think, but you don't have to worry at all, if you can make a breakthrough, the National Defense and Military Industry Research Institute is not a problem at all, you will know in the future." ”

Mu Jingchi was skeptical, but he still chose to believe Professor Yang.

After all, this belongs to the future, and there are other ways to do it, such as resigning from Huaqing University and then entering the National Defense and Military Industry Research Institute!

"If that's the case, then I'll stay on and start as a teaching assistant. ”

Yang Wenwu took out an application form and handed it to Mu Jingchi, "You fill in this form, and here fill in the course you want to choose." ”

Mu Jingchi filled in one by one according to the guidance of Professor Yang Wenwu, and the course he chose was "Fundamentals of Materials Science".

"Fundamentals of Materials Science" is divided into two parts at Huaqing University, students complete it in two semesters, and the teacher is Professor Tian Botian. In the future, Mu Jingchi became Professor Tian's teaching assistant.

"The process will take a few more days, and then I'll take you to see Professor Mita. ”

Mu Jingchi nodded.

···

It was already an hour later when I came out of Professor Yang's office.

Yang Wenwu and Mu Jingchi also talked about some issues about material knowledge, which was an inspection of Mu Jingchi's homework to see if he relaxed his requirements during the winter vacation.

"What's wrong with you scratching your ears and cheeks?"

Zhang Chuyang's desk was not far from Mu Jingchi, and he saw Zhang Chuyang who was very distressed at a glance. With the bonus of a good mood, Mu Jingchi walked over to express his concern, "The project is not going well?"

You don't need to look up to know who the speaker is, and Zhang Chuyang did it, his eyes were still staring at the information in front of him.

There are a lot of annotations on the materials, including translations of English words, some underlined points, and some traces of calculations, which seem to be very attentive to Zhang Chuyang.

"It's not a problem with the project," Zhang Chuyang shook his head, "Chizi, how are your fracture mechanics?"

With the development of production, the use of new materials, the complexity of load conditions and working conditions, newer and higher requirements are constantly put forward for the design of materials, and the traditional strength theory is also challenged.

For example, many materials need to be subjected to alternating loads over time, or work in high temperatures for a long time, and in these cases, more influencing factors must be taken into account in the calculation of strength, stiffness, and stability of materials.

Another example is the development of aerospace and aviation, and the emergence of composite materials.

In order to solve these new problems, composite mechanics and fracture mechanics were born.

"Not very good. ”

Mu Jingchi shook his head, indicating that there was nothing he could do.

Fracture mechanics is a new branch of solid mechanics to study the strength and life of cracked components, and is the theoretical basis for the design of structural damage tolerance.

It is divided into two categories: linear elastic fracture mechanics and elastoplastic fracture mechanics, the former is suitable for a small range of yield near the crack tip, while the latter is suitable for a wide range of yield near the crack tip.

Generally, it is necessary to find the fracture toughness of various materials and determine whether the object breaks under the action of a given external force, that is, to establish the fracture criterion. The crack propagation law under load is studied, and the fracture problem of objects under the simultaneous action of corrosive environment and stress is studied.

It has been widely used in aviation, aerospace, transportation, chemical industry, machinery, materials, energy and other engineering fields.

Zhang Chuyang's research project is the failure analysis of mechanical parts, and it is a relatively in-depth theoretical research direction, and fracture mechanics is bound to be proficient.

It's just that fracture mechanics in our country developed somewhat late.

Mu Jingchi is not as good as Zhang Chuyang in fracture mechanics, and the "Fundamentals of Materials Science (2069 Edition)" from the next 50 years has no relevant knowledge about fracture mechanics.

"It's so hard!"

Zhang Chuyang lamented, although there is no easy direction for the study of materials science, he still feels that fracture mechanics is difficult.

Mechanics, there is no such thing as simple!

"It's hard for me!"

Mu Jingchi seemed to be influenced by Zhang Chuyang, and when he thought of the relevant topics he would do in the future, he also sighed.

After all, now he has only received "Fundamentals of Materials Science (2069 Edition)", which is really a drop in the ocean compared with the entire material knowledge system.
