Webstresses and strains, respectively. In the static boundary condition (4), vector t¡ deflnes the tractions prescribed on portion ¡¾ of the boundary and the boundary equilibrium matrix N collects the components of the unit outward normal vector associated with the difierential operators present in the domain equilibrium matrix D. WebThe performance of the hybrid-stress element in crack modelling is assessed using benchmark tests. These tests are also used to illustrate the reduction in the order of the singularity and on the stress intensity factors that can be attained by repairing active cracks.
