Tanh1D

Uniaxial Elastic Material Using $\tanh$

Syntax

material Elastic1D (1) (2) [3]
# (1) int, unique material tag
# (2) double, elastic modulus
# [3] double, density, default: 0.0

Theory

The constitutive equation is defined as

$$\sigma=E\tanh(\epsilon),$$

where $E$ is the elastic modulus and $\epsilon$ is the strain.
