A Cohesive Segments Approach For Dynamic Crack Growth
Abstract In the cohesive segments method, a crack is represented by a set of overlapping cohesive segments which are inserted into finite elements as discontinuities in the displacement field using the partition-of-unity property of shape functions. The evolution of decohesion of the segments is governed by a relation between the displacement jump and traction across the segment. The formulation permits both crack nucleation and discontinuous crack growth to be modelled. Here, the cohesive segments formulation for dynamic crack growth is presented and application of the methodology is illustrated in two numerical examples.
