Finite element modelling of inter-ply delamination and intra-yarn cracking in textile laminates

The aim of the current study is to demonstrate the effect of inter-ply delamination on stiffness degradation of multi-ply woven composites. Such a demonstration becomes possible due to new technique of modelling textile laminates. It is based on set of boundary value problems for unit cell of a single ply, where boundary conditions imitate interaction with the other plies. Once these problems a...

The Formation and Effect of Outer-Ply Microcracks in Cross-Ply Laminates: A Variational Approach

The microcracking process in laminates which have outer-ply 90◦ plies (e.g. [90m/0n]s) has some important differences from the microcracking process in laminates which lack outer-ply 90◦ plies (e.g. [0n/90m]s). Foremost among the differences is the characteristic damage state. [90m/0n]s laminates form antisymmetric or staggered microcracks while [0n/90m]s laminates form symmetric microcracks. T...

Acoustic emission monitoring of degradation of cross ply laminates.

The scope of this study is to relate the acoustic activity of damage in composites to the failure mechanisms associated with these materials. Cross ply fiber reinforced composites were subjected to tensile loading with recording of their acoustic activity. Acoustic emission (AE) parameters were employed to monitor the transition of the damage mechanism from transverse cracking (mode I) to delam...

Deflection of Cross-Ply Composite Laminates Induced by Piezoelectric Actuators

The coupling effects between the mechanical and electric properties of piezoelectric materials have drawn significant attention for their potential applications as sensors and actuators. In this investigation, two piezoelectric actuators are symmetrically surface bonded on a cross-ply composite laminate. Electric voltages with the same amplitude and opposite sign are applied to the two symmetri...

Mechanisms of the penetration of ultra-high molecular weight polyethylene composite beams

A number of mechanisms have been proposed for the penetration of laminates comprising ultra-high molecular weight polyethylene (UHMWPE) fibres in a polymeric matrix. Two-dimensional ballistic experiments are conducted in order to directly observe the transient deformation and failure processes occurring immediately under the projectile via high-speed photography. Two sets of experiments were co...
