The Appliaction of the Finite Element Method to Fracture Mechanics Problems
A new finite element which adequately represents the character of<br/>the strains near the crack-tip is presented. The element is based on displacement functions, derived from, assumed simple strain functions, by integrating the strain - displacement equations. The resulting displacement functions …

Application of fracture mechanics to predict the growth of single and multi-level delaminations and disbonds in composite structures
… structures were identified, from which the crack tip element (CTE) approach and the virtual crack closure technique (VCCT) were selected for assessment. Extensive validation of these fracture mechanics methods is presented on a number of composite structures ranging from coupons to large …

Solving three-dimensional problems in natural and hydraulic fracture development : insight from displacement discontinuity modeling
… 3-D displacement discontinuity (DD) boundary element modeling to investigate the following intrinsically 3-D natural or hydraulic fracture propagation problems: the effect of fracture height on lateral propagation of vertical natural fractures, joint development in the vicinity of normal …

Crack growth, singularities and wave propagation in auxetic composite materials
… dissimilar materials and the singularity at the tip of interfacial crack have been studied where the bi-material contains an auxetic material. The main goal was to investigate the effects of the auxetic behavior on the singularities. We have determined that the auxetic material has a significant …
