Damage in Textile Laminates of Various Inter-ply Shift
Deformation mechanisms and failure of textile laminates are strongly affected by inter-layer configurations – a mutual shift of the plies. To model it within a traditional framework, one must construct a representative volume element (RVE), which includes all the plies. This is a time consuming and computationally expensive work. As an alternative, the paper suggests boundary conditions (BC) im...
متن کاملAcoustic 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...
متن کاملThe 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...
متن کاملDeflection 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...
متن کاملSimulation of Damage on Laminates
In this paper, we present a recently developed progressive damage model for composites (CPDM) that allows the switching between different damage modes during the numerical process to mimic real physical behaviour. The modelled damage modes are ranging from matrix cracking to fibre breakage or delamination. Moreover, the CPDM is flexible in the sense that provides the basic structure to include ...
