Z-pinned composite laminates have been increasingly applied to aircraft and other
lightweight products. This paper reviews published multi-scale research into polymer …

The curing process generates thermal residual stress in z-pinned composites, leading to
partial or complete cracking along z-pin/composite interfaces. In this study, we applied a …

A mode-I type of crack propagation and branching on account of fracture energy failure
mechanisms methodology is investigated in unidirectional (UD) fiber reinforced epoxy sheet …

Large scale fiber bridging ahead of the crack tip of ENF specimen is one of the most
common toughening mechnisms, leading to a significant resistance phenomenon on the …

A novel micro-mechanical modeling approach is developed to predict the partially
debonding of a Z-pin reinforced composite laminates after the cure process. Cohesive zone …

In this work, a numerical simulation was conducted to investigate the lamina fracture and
progressive interlaminar failure behavior of a dovetail specimen of composite fan blades …

To use effectively the shell in high-performance applications, analyzing the effect of
hygrothermal effects on a piezoelectric delamination event is necessary. A laminated …

This study investigates the influence of discrete through-thickness reinforcement, ie Z-pins,
on the through-thickness tensile strength (TTS) of curved laminates through four-point …

In this paper, we studied the curing process and curing-induced warpage of multi-pinned
composite structures through a novel multiscale methodology. This method interconnects …

A finite element model of a z-pin reinforced composite pi joint has been developed and
correlated against experimental results. A smeared cohesive zone modeling approach was …
