Research abstract
Composite delamination onset and growth prediction using commercial (COTS) finite-element codes will be facilitated by extension of cohesive element technologies. Cohesive elements eliminate the need for explicit definition and management of nodal constraints such as those required to execute Virtual Crack Closure (VCCT) methods. The Phase I project will extend cohesive element development, and implement these extensions for evaluation and validation in the ABAQUS commercial (COTS) finite-element package. Feasibility of the underlying technology will be established by application to models of actual test articles.
