Lame's Constants: Definition & Proof

[mohammed El-Kady]

TL;DR

lame's constants

what are lame's constants for material? their definitions? their proof "if exist"?

 

[Chestermiller]

They are two material properties that are required to define the stress-strain behavior of an isotropic elastic material at small deformations.

mathematically they named "lamda, mu"?. Sorry i can't write symbols on line

Yes. Those are the symbols used to represent them. They can each also be expressed in terms of the Young's modulus and Poisson ratio of the linearly elastic solid.

thank you

One way to insert symbols is to click on the SQRT icon on the toolbar in the Edit window, and select the symbol to insert into the line you are typing: λ μ

Another way is to use LaTeX to type mathematical symbols and equations. Click on INFO at the top of the page and go to "Help" to find a LaTeX tutorial...

$$\lambda \mu$$
