Member Function Documentation
◆ ComputeElasticStrain()
| void chrono::fea::ChContinuumElastic::ComputeElasticStrain | ( | ChStrainTensor<> & | strain, |
| const ChStressTensor<> & | stress | ||
| ) | const |
Compute elastic strain from elastic stress.
(using column tensors, in Voigt notation)
◆ ComputeElasticStress()
| void chrono::fea::ChContinuumElastic::ComputeElasticStress | ( | ChStressTensor<> & | stress, |
| const ChStrainTensor<> & | strain | ||
| ) | const |
Compute elastic stress from elastic strain.
(using column tensors, in Voigt notation)
◆ ComputeStressStrainMatrix()
| void chrono::fea::ChContinuumElastic::ComputeStressStrainMatrix | ( | ) |
Computes elasticity matrix and stores the value in this->StressStrainMatrix.
Note: is performed every time you change a material parameter.
◆ GetLameFirstParam()
|
inline |
Get Lame first parameter.
The second is shear modulus, which can be obtained via GetShearModulus().
◆ GetPWaveModulus()
|
inline |
Get P-wave modulus.
If V=speed of propagation of a P-wave, then (M/density)=V^2.
◆ SetPoissonRatio()
| void chrono::fea::ChContinuumElastic::SetPoissonRatio | ( | double | v | ) |
Set the Poisson ratio.
The Poisson ratio is set as v = -transverse_strain/axial_strain, so that it takes into account the 'squeezing' effect of materials that are pulled. Note: v = 0.5 means perfectly incompressible material, that could give problems with some type of solvers. Setting v also changes G.
◆ SetRayleighDampingAlpha()
|
inline |
Set the Rayleigh mass-proportional damping factor alpha.
This builds the damping R as R = alpha*M + beta*K
◆ SetRayleighDampingBeta()
|
inline |
Set the Rayleigh stiffness-proportional damping factor beta.
This builds the damping R as R = alpha*M + beta*K
◆ SetShearModulus()
| void chrono::fea::ChContinuumElastic::SetShearModulus | ( | double | G | ) |
Set the shear modulus G.
Setting G also changes Poisson ratio v.
