Wedge and crack solutions for Mindlin–Reissner plates

Displacement potentials are used to define the complete set of displacement and stress-resultant fields in moderately thick plate bending problems. The asymptotic singular terms are used to define and solve the eigenproblems associated with all alternative homogeneous wedge boundary conditions, and extended to model bimaterial wedges. This solution is used to model edge cracks with a filler and thus simulate the effect of crack repair. Definitions for the stress intensity factors are given, as well as the constitutive relations used to model a repaired crack with a contact element.
