A stable method of calculation of the electromagnetic response of planar anisotropic laminates to an active source with limited distribution along the strata direction is developed. The laminates can be sandwiched between isotropic, anisotropic, or perfectly conducting covers/substrates. The source is either inside the laminates or in the cover or substrate. Based on the propagator matrix metho...

Composites are becoming anessential part of today’s material because they offer advantagessuch as low weight, corrosion resistance, high fatigue strength; faster assembly etc. composites aregenerating curiosity and interest all over the worlds.The objective of this research is to provide the simulation methodology for natural fiber composites to predict the tensile strength using FEA tool: ANSY...

Corrosion of steel reinforcement is one of the main durability problems facing reinforced concrete infrastructures worldwide. This paper will summarize the results of a multi-phase experimental program undertaken at the University of Waterloo to investigate the viability of using externally bonded fiber reinforced polymer (FRP) laminates to rehabilitate corrosion-damaged reinforced concrete bea...

Running title: A new cohesive model for simulating delamination propagation in composite laminates 2 Abstract In this paper, we propose a new cohesive model to stably and accurately simulate the delamination propagations in composite laminates under quasi-static and low-velocity impact tr...

The effects of through-thickness reinforcement of carbon/epoxy laminates with thin pins on the in-plane tensile properties, tensile fatigue life and failure mechanisms are investigated. Tensile studies in the 0 fibre direction are performed on unidirectional and quasiisotropic laminates reinforced with different volume contents and sizes of fibrous composite z-pins. Microstructural analysis rev...

Fibre metal laminates (FMLs) have appeared as the most suitable materials for shipbuilding, aeronautical and aerospace applications due to their superior mechanical properties over traditional materials. In this paper, degradation in flexural and impact properties of glass fibre/epoxy composite (GF/E composite) and stainless steel glass fibre/epoxy fibre metal laminate (SS FML) due to hygrother...

This paper developed three-dimensional (3D) Finite Element Analysis (FEA) to investigate the effect of fibre lay-up on the initiation of failure of laminated composites in bending. TsaiHill failure criterion was applied to identify the critical areas of failure in composite laminates. In accordance with the 3D FEA, unidirectional ([0]16), cross-ply ([0/90]4s) and angle-ply ([±45]4s) laminates m...
