A New Progressive Curvilinear Strain Energy-Based Crack Growth Modeling Algorithm Using Multicomplex Variable Finite Elements

Abstract:

Arbitrary, non-planar progressive fracture analysis is of critical importance to the integrity of structures. While significant progress has been made in the last 25 years, there are still technical issues regarding computational expense, robustness, and accuracy. Based upon the recent significant enhancements available through the use of multicomplex finite element methods, a new high-order progressive strain energy based progressive crack growth algorithm is proposed.
