Abstract
|
The material force approach is an efficient, elegant, and accepted means to compute the J-integral as a fracture mechanical parameter for elastic and inelastic materials. With the formulation of a multiplicative split of the deformation gradient at hand, rate-dependent (visco-elastic) materials described for example by the physically based Bergström-Boyce model can be investigated. For these investigations, the so-called material volume forces have to be computed in order to separate the driving forces acting on the visco-elastic zone around the crack tip from the driving forces acting on the crack tip itself, representing the crack driving force. To illustrate the effectiveness of this approach, the so-called dwell-effect of elastomeric materials is investigated.
