tensormesh.material

Isotropic linear-elastic material model and a small set of preset instances used throughout the solid-mechanics examples.

IsotropicMaterial

Preset materials

The module also ships ready-to-use IsotropicMaterial instances with literature values. Import directly:

from tensormesh.material import Steel, Aluminum, Rubber, Glass

Preset	Young's modulus \(E\)	Poisson's ratio \(\nu\)	Density \(\rho\)	Notes

Aluminum	70 GPa	0.33	2700 kg/m³	\(\sigma_y = 100\) MPa, \(H = 700\) MPa
Rubber	10 MPa	0.48	1100 kg/m³	near-incompressible
