For Linear strain softening or Exponential strain softening enter the Tensile strength σts, the default is to take the value From material. Also select the type of Tensile strain softening and enter the Fracture energy per area Gft, the Fracture energy per volume gft, or the Strain softening parameter εft accordingly.

For Mazars damage evolution function, enter the Tensile strain threshold ε0t, and the Tensile damage evolution parameters At and Bt.

For the Crack band method select the type of Crack band calculation — Element volume/area, or Element size. Note that when the Crack band method is selected, only the Fracture energy per area is available as Strain softening input.

|
For the Implicit gradient method enter the Internal length scale lint. If the Fracture energy per area was selected as Strain softening input, enter also the Characteristic size of the damage dissipation zone hdmg.
|
When a Mixed Formulation is selected in the parent Linear Elastic Material, the damage model can give spurious results. The Implicit gradient regularization method is more stable in this respect, and it is recommended when using the mixed formulation.
