3.1.5.28. TensionOnly Material Wrapper

This command is used to construct a TensionOnly uniaxial material wrapper. The wrapper returns zero stress and zero tangent when the wrapped material would return negative stress; it does not call commitState() on the wrapped material when stress is negative. So only tensile (positive) stress is returned.

uniaxialMaterial TensionOnly $matTag $otherTag <-min $minStrain> <-max $maxStrain>

Argument	Type	Description
$matTag	integer	unique material tag
$otherTag	integer	tag of a previously-defined UniaxialMaterial
$minStrain	float	(optional) minimum strain limit
$maxStrain	float	(optional) maximum strain limit

Example

1. Tcl Code

uniaxialMaterial Elastic 1 100.0
uniaxialMaterial TensionOnly 2 1

2. Python Code

ops.uniaxialMaterial('Elastic', 1, 100.0)
ops.uniaxialMaterial('TensionOnly', 2, 1)
