Abstract

In this paper computational modeling and simulation of the contact response of the quasi- isotropic carbon fibrous composite panels against blunt nose tip indenters has been studied.\n Mathematical modeling of spatial contact interaction was developed and incorporated into the finite element analysis software ABAQUS using implicit dynamic integration routine. Effect of ply orientation, thickness, indenter size, and variable loads were studied. From the comparisons of stresses, strains and deflections for isotropic and quasi-isotropic materials, it was observed that laminate thickness, material properties, loads and indenter sizes have significant affect on individual plies. The approach significantly reduces complexity in modeling some of the similar problems. The obtained results could be useful in improving the simulation modeling for design parameters. The selected results are included in the forms of graphs, contour plots and legend Tables.
