This paper presents buckling studies made on skew plates using finite element. The effects of the skew angle, aspect ratio, length-to-thickness-ratio, fibre orientation angle, and numbers of layers in the laminate and laminate sequence on the critical buckling load factor (Kcr) of antisymmetric composite laminates have also been presented. The critical buckling load factor (Kcr) is found to inc...

The stability and low melting point make ionic liquids favorable electrolytes to be used in a wide range of electrochemical systems. The application field includes lithium ion batteries, electric doublelayer capacitors (EDLCs), and ionic electromechanically active polymer (iEAP) actuators. The iEAP is a laminate structure that consists of electronically conductive high surface area electrodes b...

introduction: the purpose of the presented study was to evaluate the effect of zirconia thickness on the tensile stress of zirconia based all-ceramic restorations. methods: twenty zirconia disks with 10mm diameter were prepared in two groups using cad/cam system. the thickness of zirconia was 0.5mm in first group and 0.3mm in second group. after sintering, 0.4mm glass ceramic porcelain was appl...

Abstract Hybrid laminates with continuous fiber reinforcement, such as glass reinforced aluminium laminate (GLARE), aramid aluminum (ARALL), or carbon (CARALL), have been developed to increase the lightweight potential and fatigue resistance applied for aircraft structures. However, use of thermosetting matrices imposes material limitations regarding recycling, malleability, manufacturing-cycle...

The fiber-metal composites made of aluminum sheets and glass fibers reinforced with a polyester resin as the matrix were studied. prepared by hand lay-up method. Some aspects manufacturing affecting composite behavior considered. In particular, influences arrangement layers their number on mechanical physical properties ten different compositions investigated. addition two densities tensile mod...

This paper studies interfacial mechanical behavior of laminate beams, consisting of two piezoelectric facial sheets and an elastic core. The study is based on coupled multi-filed finite element formulation. The emphasis is placed on mechanical and electric behavior of interfaces between piezoelectric material and elastic material, including effect of geometrical parameters, stress distribution ...

Beam theory analysis was applied to predict delamination growth in DCB specimens reinforced in the thickness direction with pultruded pins, known as Z-fibers. The specimen arms were modeled as cantilever beams supported by discrete springs, which were included to represent the pins. A bi-linear, irreversible damage law was used to represent Z-fiber damage, the parameters of which were obtained ...
