The Literary Life of a Science Leader

Chapter 147 Mechanics of Elasticity (2051 Edition)

"There are many people and strength, and the progress is not bad."

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

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

"In the past, the four of us could only try our luck a little bit. Now that the project team has grown in size, although we won't be able to break through immediately, the path is much clearer than before."

Mu Jingchi's theory is a whole system, just like a tree with many forks.There are naturally many directions that can be taken, and the scientific research results that can be produced in the end are as many as the leaves.

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

"The engineering group, the experimental group, the theoretical group, and the calculation group are divided into small projects, and a small project is divided into four groups. In just one month, good progress has been made."

Looking at these data results, Mu Jingchi analyzed them seriously, with a smile on the corner of his mouth.

"It seems that the second stage of positive edge dislocation should not be far away."

Mu Jingchi knows that in the entire future dislocation theory system, edge dislocation and screw dislocation are relatively simple, and they are independent.But the third kind of mixed dislocation is diverse, changeable and irregular, and it is more difficult.

Just when he was in a happy mood.

A more pleasant voice sounded.

"Ding, the 'knowledge extraction' function is triggered, 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"

"Elasticity (2051) Edition"

"Analytical Mechanics (2051 Edition)"

"it is good!"

Mu Jingchi secretly shouted in his heart, very excited, "Triggered just after returning, Ouhuang!"

He skipped the first related knowledge directly and focused on the latter two knowledge.

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

It can guide current scientific research very well.

As for the knowledge that is too far away, Mu Jingchi is actually not too cold.

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

Don't look at the gap of only 80 years, but it is actually very far away.

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

Both theory and application.

Although some basic material research seems to be a paper on water, some of these scientific research results are the basis for future material research.

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

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 strong, and he couldn't cross this gap at all.

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

Elastic mechanics and analytical mechanics in the current era are actually basic knowledge, at least for Mu Jingchi now, but not in 2051, there is a gap of 31 years.

31 years is not long.

Even if there is a gap in knowledge, it will not be too serious. Mu Jingchi can fully demonstrate it again with the help of scientific research ability.Just like the dislocation theory system research she is doing now.

"Let me take a serious look."

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

Brow wrinkled.

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 and became a little more serious.Since the language is not the mother tongue, then more energy must be devoted to the language.

Elasticity is a branch of solid mechanics.

It studies the internal force state and deformation law of elastic bodies caused by loads.Load refers to mechanical force, temperature, electromagnetic force and other physical factors that can cause deformation of objects and generate internal force; elastic body refers to a deformable body that is different from rigid bodies in theoretical mechanics, and can completely restore its original shape and size after unloading .

After mastering the internal force and deformation laws of objects, 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 it sound similar to Mechanics of Materials?
In fact, elasticity and mechanics of materials are the same in terms of basic tasks, both to obtain more perfect components.But their research objects are not the same.

Mechanics of materials basically only studies the stress-strain problems of rod-shaped structures under the action of external forces.

The research scope of elastic mechanics is wider, deeper and more precise than that of material mechanics.

There are also great differences in the research methods of the two, specifically up to now: In addition to analyzing statics, geometry, and physics when studying problems, mechanics of materials also introduces a large number of assumptions about the stress and strain of components. Greatly simplifies mathematical calculations.

But the error of the result will be relatively large.

Elastic mechanics basically does not make other assumptions except for the five basic assumptions, and the results derived from pure mathematical theory are much more accurate than material mechanics.

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

"This 2051 version of knowledge is elastic mechanics that includes both mathematics and applications!"

Just after Mu Jingchi read the previous content, he knew the knowledge framework of elastic mechanics.

The English in 2051 has not changed much. Even if there are newly created English words, Mu Jingchi can guess the general meaning based on the prefix, suffix, and splicing of the word, so it is not difficult to understand.

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

Basic equations and general theorems of elastic mechanics; Cartesian and polar coordinate solutions for plane problems; stress tensor and stress-strain relationship; governing equations and solution methods for spatial problems; basic equations and spatial symmetry problems in orthogonal curvilinear coordinates The solution of the Navier-Lame-Poole equation and its application; the torsion of the cylindrical body and so on.

There are naturally small chapter directories under the big chapter directory, but compared with Huaxia's directory classification, there are not many, very few.

There are even fewer sub-categories than the modern elastic mechanics chapter, which makes Mu Jingchi feel a little strange.

However, he didn't go into this knowledge carefully to savor, but pulled out of this elastic mechanics and entered into another analytical mechanics.
