The elastic material class for MPM.

Parameters:

• E (float, optional) – Young’s modulus. Default is 3e5.

• nu (float, optional) – Poisson ratio. Default is 0.2.

• rho (float, optional) – Density (kg/m³). Default is 1000.

• model (str, optional) – Stress model (‘corotation’, ‘neohooken’). Default is ‘corotation’.
