Dynamic Analysis of Interfacial Cracks in Composite Laminates
The interfacial crack in composite laminates has been of great interest as composite materials are widely used today. In this paper, the order of dynamic stress singularity of interfacial cracks is derived, and a hybrid finite element method is successfully developed for this problem. Both the …

Application of the finite element method to problems in fracture mechanics
… the application of the finite element method to cracked structures. The present work was directed towards the establishment of a comprehensive two-dimensional finite element, linear elastic, fracture analysis package. Significant progress has been made to this end, and features which can now be …
