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 …

Multiple Wave Scattering and Calculated Effective Stiffness and Wave Properties in Unidirectional Fiber-Reinforced Composites
… m, B and Y for fiber-reinforced composites with interfacial layers between fibers and matrix. The material properties of the layers are assumed to be either linearly or exponentially distributed between the fibers and matrix. A concise formula is obtained where parameters can be computed using a …

HYGROTHERMALLY-INDUCED DELAMINATION AND CRACKING IN PLASTIC IC PACKAGES
… may exist in bonded interfaces. These small interfacial defects induce very high stress concentrations around the defects leading to debonding and delamination growth. If the total stress intensity factor generated by the loading due to the hygrothermal stresses and steam pressure is higher …

Sensitivity Analysis of Interface Fatigue Crack Propagation in Elastic Composite Laminates
… of the work shed more light on mechanisms of interfacial crack propagation under cyclic shear in the case of a curved B/Ep-Al composite laminate. Moreover, the outcome of the sensitivity gradients demonstrated some advantages for using the sensitivity analysis to pinpoint directions for the …
