The objective of this work is to propose and implement finite element models ABAQUS dedicated to the analysis of mechanical tests intended for the characterization of materials laminated carbon epoxy composites. The composite material GODT No. 1 which illustrates this study consists of unidirectional fabrics of carbon and epoxy resin.
In this project, I worked on modeling the behavior of composites structures starting from the constituent behaviors, the calculations are performed at various scales from the single ply to the complete laminate theory, and finite element analysis by using Abaqus for different composites structures like cantilever beam, tensile and bending test, simple truss element, bridge structures, steady state heat conduction, and response of stiffened square plate subject to blast loading, laminated composite plates, etc.
Following tasks were performed ;
​Assignment of sections, material properties (Uni-directional glass-epoxy resin composite), boundary conditions and loading parameters in-line with the test data followed by meshing of the shell in order to perform simulations.​
Run simulations and study the results for various configurations/orientations of the plies.
Analytical calculation of the maximum ply selection for a particular configuration based on TSAI-WU/TSAI-HILL criterion's and re-run the simulations for validation of the data.
Extend the optimal ply configuration data determined to various composite models and check for failures.
Simulation of three point bending test on a triangular composite section (pre-defined dimensions) in ABAQUS and compute the best configuration as well as the number of plies for the section based on the failure criterion's.
