Topic: 1
Abstract:
The dislocation-based fracture or distributed dislocation technique is rather well known within classical elasticity. Here, we will focus on its application to present nonsingular models of cracks in generalized continua. Nonlocal and gradient elasticity will be employed to present nonsingular fields of crack of mode III. Considering the nonstandard boundary conditions in gradient elasticity, the appropriate boundary conditions will be studied. An incompatible framework will be used for the dislocation-based approach.
