XFEM Damage Analysis of Carbon Fiber Reinforced Composites and Crack Propagation in Mixed-Mode and Implementation of the Method Using ABAQUS

Abstract—There are numerous numerical studies of particle interface debonding based on the cohesive zone models, In order to validate the integrity of aerospace structures to fatigue damage the study of existing cracks must be studies closely. By applying multiscale method to fiber reinforced composites to study the multicrack behavior and fracture mechanics by using the cohesive zone modelling in ABAQUS with all the necessary parameters. Getting started with a single crack response followed by delamination and then introduced the study for two cracks to validate the results by simulations and experimentations as the same time. Multiscale modelling of CFRCCs executed as a strong and reliable tool for the study of crack propagation further simulating the structural model in different possible conditions. The structure may pertain to any assembly or part depending upon boundary conditions, loading and other parameters. “Carbon fiber reinforced plastics are mostly used in laminates, which consist of several very thin layers piled over each other. The study of these layers is composed of either unidirectional fibers or textile reinforcements which are inserted in an epoxy resin”. This 3D material model is incorporated into a solid-shell finite element. A promising strategy to increase the tensile failure strain of carbon fibre-reinforced composites is to hybridise carbon fibres with other, higher-elongation fibres. The procedure of applying cohesive elements in ABAQUS software`s subroutines to model 3D complex crack propagation in different conditions and states.
