Buckling, Post Bucklingand Progressive Damage Analysis of Woven Glass/Epoxy Composite Laminate by ANSYS

Present work mainly deals with the progressive damage, buckling and post buckling of composite laminated plate. Woven glass/epoxy unidirectional has been taken for analysis. For finite element analysis Ansys 17.0 is used which is a commercial tool for modelling. In research work Non-linear bifurcation method is used. Hashins criteria is used for progressive damage analysis and eigenvalue buckling is done for buckling and post-buckling analysis. Effect of change in ply orientation is reviewed followed by effect of change in length and thickness. Effect of the change in dimensions can also be seen in the validation part. Buckling under mix loading condition i.e. compression with shear loading is viewed under different proportions and for different thickness. Matrix failure occurs mainly in specimen while compression loading condition in case of buckling the critical buckling load was very low compared to that of the progressive damage failure. In case of mix loading effect found for specimens under lower length to thickness ratio is less compared to that of specimens under higher length to thickness ratio.
