MultilinearElastic1D

Uniaxial Multilinear Elastic Material

Theory

A simple uniaxial multilinear elastic material model. The BilinearElastic1D model is a special case of this model.

Syntax

material MultilinearElastic1D (1) (2 3...) [4]
# (1) int, unique material tag
# (2) double, strain of the data point
# (3) double, stress of the data point
# [4] double, density, default: 0.0

Usage

The first point does not need to be origin. Starting from the first non-zero point is fine. Multiple data points can be defined. A constant response is assumed after the last point.

material MultilinearElastic1D 1 1E-3 35 2E-3 40 3E-3 45 4E-3 30
