calculate_elastic_moduli

torch_sim.elastic.calculate_elastic_moduli(C)

Calculate elastic moduli from the elastic tensor.

Parameters:

C (Tensor) – Elastic tensor (6x6)

Returns:

Four Voigt-Reuss-Hill averaged elastic moduli in order:

• Bulk modulus (K_VRH)

• Shear modulus (G_VRH)

• Poisson’s ratio (v_VRH), dimensionless

• Pugh’s ratio (K_VRH/G_VRH), dimensionless

Return type:
