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.
