Compute Isotropic Elasticity Tensor
Compute a constant isotropic elasticity tensor.
Description
The material ComputeIsotropicElasticityTensor
builds the isotropic elasticity (stiffness) tensor with two user provided elastic constants.
The isotropic elasticity tensor is given, in engineering matrix notation (Malvern, 1969), as (1)
ComputeIsotropicElasticityTensor
accepts as an argument two of five isotropic elastic constants: lambda , the shear modulus , the bulk modulus , the Young's modulus , or the Poisson's ratio . The material includes the conversions into Lame constants, see Slaughter (2012) for the conversion equations among the isotropic elastic constants.
An automatic differentiation version of this object is available as ADComputeIsotropicElasticityTensor
.
