"There is strength in numbers, and progress is good. ”

Mu Jingchi looked at the data in the study, analyzed them one by one, and muttered in his heart.

These data are national defense communications, so Mu Jingchi still doesn't need to worry about data security.

"Before, the four of them could only try their luck a little bit, but now the project team is huge, although it will not be able to break through immediately, but the road is much clearer than before. ”

Mu Jingchi's theory is a whole system, just like a tree, with a lot of forks on it. Naturally, there are many directions that can be taken, and in the end, there are as many scientific research results as the leaves.

However, not all scientific research results can be applied, and more become part of the theoretical system.

"The engineering group, the experimental group, the theoretical group, the calculation group, and the project are divided into small projects, and a small project is divided into four groups, and in just one month, there is good progress. ”

Looking at these data results, Mu Jingchi analyzed them seriously, and the corners of his mouth outlined a smile.

"It seems that the second stage of the orthogonal dislocation should not be far off. ”

Mu Jingchi knows that in the whole future dislocation theory system, blade dislocation and spiral dislocation are relatively simple, and the two are independent. But the third type of mixed dislocation, which is diverse, changeable and irregular, is more difficult.

Just when he was in a happy mood.

A more pleasant voice sounded.

"Ding, the 'knowledge extraction' function is triggered, and the acquired knowledge has been stored in the system, and the host can view it at any time. ”

Mu Jingchi was excited, and immediately opened the knowledge stored in the system.

"Truth Capture"

Elastic Mechanics (2051) Edition

Analytical Mechanics (2051 Edition)

"Good!"

Mu Jingchi secretly shouted in his heart, very excited, "Just come back and trigger, Emperor Ou!"

He skipped the first related knowledge directly, and the focus was on the latter two knowledge.

Truth be told, it's this kind of futuristic basics that he likes. Because the foundation of the future is the future knowledge of the present, and it is very important and correct knowledge and direction.

Able to guide current scientific research very well.

As for knowledge that is too distant, Mu Jingchi is actually not too cold.

For example, "Mechanics of Materials (2100 Edition)", although material mechanics and theoretical mechanics and structural mechanics are called the three major mechanics, the 2100 edition is too far away.

Don't look at it as an 80-year gap, but it's actually very far away.

Materials are different from physics and mathematics, and the theoretical path of mathematics and physics is not as vigorous and rapid as before, but materials have been improving.

Both theoretically and practically.

While some of the basic materials research appears to be water papers, some of these scientific findings are the basis for future materials research.

By the year 2100, it can be said that there is almost a difference between heaven and earth from the current material world.

Therefore, the 2100 version of material mechanics extracted by the system last time, Mu Jingchi felt very difficult, because the knowledge gap in it was too powerful, and he couldn't cross this fault at all.

But this knowledge of elastic mechanics and analytical mechanics in 2051 is very suitable for the current Mujingchi.

Elastic mechanics and analytical mechanics in the current era are actually basic knowledge, at least for the current Mujingchi, but not in 2051, there is a 31-year gap in between.

31 years, not long.

Even if there is a knowledge gap, it will not be too serious, and Mu Jingchi can fully use his scientific research ability to show it again. Just like what she is doing now.

"Let me take a serious look. ”

Mu Jingchi first opened "Elastic Mechanics (2051 Edition)".

His brow furrowed.

It's actually in English.

The knowledge extracted by the system before was all in Chinese, but I didn't expect it to appear in English now.

Mu Jingchi twisted his neck, a little more serious. Since the language is not the mother tongue, it is necessary to devote more energy to the language.

Elastic mechanics is a branch of solid mechanics.

It studies the state of internal forces and deformation laws of elastomers due to loads. Load refers to various physical factors that can cause deformation and internal force of an object, such as mechanical force, temperature, electromagnetic force, etc., and elastomer refers to a deformable body that is different from a rigid body in theoretical mechanics, which can completely restore its initial shape and size after unloading.

After mastering the internal forces and deformation laws of the object, it is not difficult to determine the strength, stiffness and stability of structural components and machine parts, so as to achieve the purpose of implementing or improving the design of structures and parts.

Does that sound similar to the mechanics of materials?

In fact, elastic mechanics and material mechanics are the same in terms of the basic task, both in order to obtain more perfect components. But the objects of study are not the same.

Fundamentally, the mechanics of materials only studies the stress-strain of rod-like structures under the action of external forces.

The scope of study of elastic mechanics is broader, deeper, and more precise than that of material mechanics.

The two are also very different in terms of research methods, and the specific ones are as follows: in addition to analyzing the three aspects of statics, geometry and physics, the mechanics of materials also introduces a large number of assumptions about the stress and strain of components, which greatly simplifies the mathematical calculation.

However, the error in the results will be relatively large.

In addition to the five basic assumptions, elastic mechanics basically does not make other assumptions, and the results obtained are much more accurate than those of material mechanics.

Of course, elastic mechanics can also introduce additional assumptions about deformation and stress, just like material mechanics. If it is not introduced, it is mathematical elasticity, and if it is introduced, it is applied elasticity.

"This 2051 version of the knowledge is elastic mechanics that is included in both mathematics and application!"

Mu Jingchi has just finished reading the previous content, and he knows the knowledge framework of elastic mechanics.

There are not many changes in English in 2051, and even if there are newly created English words, Mu Jingchi can guess the approximate meaning based on the prefixes, suffixes, and splices of the words, so it is not difficult to understand.

This knowledge of elastic mechanics naturally has a catalog, and Mu Jingchi's consciousness circulates in the catalog.

The basic equations and general theorems of elastic mechanics, the Cartesian coordinate solution and the polar coordinate solution method of plane problems, the stress tensor and stress-strain relationship, the governing equations and solutions of space problems, the basic equations in orthogonal curvilinear coordinates and the solution of spatial symmetry problems, the general solution of the Navier-Lame-Poole equation and its application, the torsion of cylindrical bodies, etc.

Naturally, there are small chapter catalogs under the large chapter catalog, but compared with the catalog classification of Huaxia, there are not many, very few.

Even less than the sub-categories under the modern elastic mechanics chapter, it is a little strange to see Mu Jingchi.

However, he did not enter this knowledge in detail to savor it, but withdrew from this elastic mechanics and moved on to another analytical mechanics.
