3.1.5.29. SimpleFracture Material Wrapper

This command is used to construct a SimpleFracture uniaxial material wrapper. The wrapper imposes tensile fracture on the wrapped material: after the strain exceeds a specified maximum tensile strain, the wrapper provides compressive stress based on an estimate of the elastic strain.

uniaxialMaterial SimpleFracture $matTag $otherTag $maxStrain

Argument	Type	Description
$matTag	integer	unique material tag
$otherTag	integer	tag of a previously-defined UniaxialMaterial
$maxStrain	float	maximum tensile strain (fracture strain)

Example

1. Tcl Code

uniaxialMaterial Hardening 1 3.0 1.0 0.1
uniaxialMaterial SimpleFracture 2 1 0.8

2. Python Code

ops.uniaxialMaterial('Hardening', 1, 3.0, 1.0, 0.1)
ops.uniaxialMaterial('SimpleFracture', 2, 1, 0.8)
