A typical connector might have pieces that break if a relative motion
component, force, or moment becomes too large.
Abaqus
provides a way to define which components of relative motion will break and the
criteria used to release these components. You can select the component of
relative motion on which the failure criterion is based.
In
Abaqus/Standard
connector failure can be used to specify connector behavior based on available
components of relative motion. In
Abaqus/Explicit
connector failure can be used to specify connector behavior based on
constrained as well as available components of relative motion. Limit values
for force or moment can be specified for all components of relative motion
involved in the connection. In addition, for connectors with available
components of relative motion, limit values can be specified for the relative
positions corresponding to an available component.
In
Abaqus/Standard
if the failure criterion specified for the selected component of relative
motion is met, either all components of relative motion fail or a single
available component fails. By default, all components of relative motion are
released upon meeting the failure criterion. The nodal force contributions for
all released components from the connector element will be removed during the
increment when the failure criterion is met.
In
Abaqus/Explicit
if the failure criterion specified for the selected component is met, either
all components or a single available component fails. By default, all
components are released upon meeting the failure criterion. The nodal force
contributions for all released components from the connector element will be
removed during the increment when the failure criterion is met.
