However, the elements still remain in the Abaqus model. Elements that have been removed are not displayed when you view the deformed model in the Visualization module of Abaqus/CAE (Abaqus/Viewer). If an element is removed, the output variable STATUS is set to zero for the element, and it offers no resistance to subsequent deformation. In Abaqus/Explicit a material point is assumed to fail when either of the damage variables associated with fiber failure modes (tensile or compressive) reaches and the element is removed from the mesh when this condition is satisfied at all of the section points at any one integration location of an element for example, in the case of shell elements all through-the-thickness section points at any one integration location of the element must fail before the element is removed from the mesh. You can reduce this upper bound as discussed in “Controlling element deletion and maximum degradation for materials with damage evolution” in “Section controls, ” Section 27.1.4.īy default, in Abaqus/Standard an element is removed (deleted) once damage variables for all failure modes at all material points reach (see “Controlling element deletion and maximum degradation for materials with damage evolution” in “Section controls, ” Section 27.1.4). By default, the upper bound to all damage variables at a material point is.
You have control over how Abaqus treats elements with severe damage. Maximum degradation and choice of element removal
