Description¶

The material type for reactive fatigue materials is reactive fatigue.

The elastic property defines the constitutive relation of the intact (unconstrained) elastic material and associated material properties for unconstrained materials (used with elastic damage). The elastic_damage or fatigue_damage properties define the cumulative distribution function and associated material properties for elastic or fatigue damage, respectively. The elastic_criterion and fatigue_criterion properties define the damage criterion for intact and fatigued bonds of the elastic solid.

Example:

<material id="1" type="elastic damage">
  <k0>0.001</k0>
  <beta>2</beta>
  <elastic type="neo-Hookean">
    <density>1</density>
    <E>200000</E>
    <v>0.3</v>
  </elastic>
  <elastic_damage type="CDF Weibull">
    <alpha>20</alpha>
    <mu>200</mu>
    <Dmax>1</Dmax>
  </elastic_damage>
  <fatigue_damage type="CDF Weibull">
    <alpha>10</alpha>
    <mu>100</mu>
    <Dmax>1</Dmax>
  </fatigue_damage>
