autopdex.models.neo_hooke

autopdex.models.neo_hooke(F, param)

Computes the strain energy for a neo-Hookean material model of Ciarlet type given the deformation gradient.

Parameters:

• F (jnp.ndarray) – Deformation gradient tensor.

• param (tuple) – Lame parameters (lambda, mu).

Returns:

Strain energy value for the given deformation gradient.

Return type:

float

Notes

• The strain energy function is based on the Ciarlet type neo-Hookean model.

• This model is suitable for large deformation analysis in hyperelastic materials.
