## Function Documentation

function [ lambda , mu ] = Compute_Lame | ( |  | E,
|  |  | nu,
|  |  | alpha
| ) |  |

Computation of Lame coefficients from Young's modulus and Poisson's ratio.

Example
  We consider the example of steel with plane strain hypothesis.

              Th=SquareMesh(10);
              E=2.1*1e11; nu=0.27; alpha=1;
              [lambda,mu]=Compute_Lame(E,nu,alpha);
              Num=0;
              K=StiffElasAssemblingP1base(Th.nq,Th.nme,Th.q,Th.me,Th.areas,lambda,mu,Num);

Parameters:

  E | Young's modulus
  nu | Poisson's ratio
  alpha | parameter such that alpha=1 <=> plane strain, alpha=0 <=> plane stress

Return values:

  lambda | First Lame coefficient in Hooke's law
  mu | Second Lame coefficient in Hooke's law
