Detailed Description

This class implements Compressible Ogden material.

Author: Martin Horák, nitra.nosp@m.mkar.nosp@m.oh@se.nosp@m.znam.nosp@m..cz

@Note References: R.W. Ogden: Non-Linear Elastic Deformations, de Souza Neto, Peric, Owen: Computational Methods for Plasticity: Theory and Applications

Free energy is considered as:

\[\rho_0 \psi = \sum_I^N \frac{mu_I}{alpha_I}(\lambda_1^{\alpha_I}+\lambda_2^{\alpha_I}+\lambda_3^{\alpha_I}-3) + \frac{1}{2} K[ln(J)]^2 \]

\( \alpha_I \), \( mu_I \), and \(K\) are material parameters.

\( \lambda_1\), \( \lambda_2 \), and \( \lambda_3 \) are principal stretches

Compressible Neo-Hookean model is obtained by setting \(N = 1\), \(\alpha_1 = 2\)

Compressible Mooney-Rivlin model is obtained by setting \(N = 2\), \(\alpha_1 = 2\), and \(\alpha_2 = -2\).
