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...
متن کاملEffect of Ply Thickness on the Damage Development in Composite Laminates (preprint)
This paper describes the experimental investigation on the effect of ply thickness on the first ply failure, delamination, and the subsequent final failure of graphite/epoxy composite laminates. The laminates considered in this paper are a cross-ply and two quasi-isotropic laminates containing thin plies in the desired interface. The onset of the first ply failure and delamination, and the stre...
متن کاملEffect of Stacking Sequence on the Temperature Distribution in a Composite Multi-ply Laminates Vessel
Due to high solidity to weight ratio of composite they have been used widely. A many all the special features of composites, the layers arrangement, heat transfer and convection in these kinds of materials are of the most important features of them. Since heat conductivity of composite are dependent on the direction, they are grouped both in isotropic and anisotropic material and thermal analys...
متن کاملComparative Analysis of Drills for Composite Laminates
The characteristics of carbon fibre reinforced plastics allow a very broad range of uses. Drilling is often necessary to assemble different components, but this can lead to various forms of damage, such as delamination which is the most severe. However, a reduced thrust force can decrease the risk of delamination. In this work, two variables of the drilling process were compared: tool material ...
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...
