Meso-scale Modeling of Tension Analysis of Pure and Intra-ply Hybrid Woven Composites Using Finite Element Method
One of the key issues associated with using of composites in various applications is their tensile behavior. The tensile behavior of a composite material is strongly influenced by the properties of its constituents and their distribution. This paper focuses on gaining some insights into the tensile process of pure and hybrid woven composite reinforced with brittle and ductile yarns. For this pu...
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 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 کاملDamage 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 کاملBuckling and vibration analysis of angle -ply symmetric laminated composite plates with fully elastic boundaries
The main focus of this paper is on efficiency analysis of two kinds of approximating functions (characteristic orthogonal polynomials and characteristic beam functions) that have been applied in the Rayleigh-Ritz method to determine the non-dimensional buckling and frequency parameters of an angle ply symmetric laminated composite plate with fully elastic boundaries. It has been observed that o...
