ElasticOS

Isotropic Elastic Material For Open Sections

Syntax

material ElasticOS (1) (2) (3) [4]
# (1) int, unique tag
# (2) double, elastic modulus
# (3) double, poissons ratio
# [4] double, density, default: 0.0

Remarks

It has two DoFs. The elastic stiffness can be expressed as

\[ \mathbf{K}=\begin{bmatrix} E&0\\ 0&\dfrac{E}{2(1+\nu)} \end{bmatrix} \]
