Abstract: Abstract:- This paper proposes an easy implicit dynamic approximation for the contact response of the quasi- isotropic composite panels with blunt indenters using Hertzian contact laws. The mathematical modelling of spatial contact interaction was developed using generalized and modified Hertz's solution. Models were incorporated into the commercially available finite element analysis software ABAQUS using implicit dynamic integration routine. The influence of various parameters like, stresses, strains and deflections were studied for isotropic and quasi-isotropic models. Moreover, effects of ply orientation, thickness, indenter size, and variable loads were also studied. It was observed that laminate thickness, load and indenter size affect the force/indentation behaviour and pressure distributions could be simulated in the routine. Stacking sequence, force/contact-length relationship effects of individual plies could also be investigated. The approach signif!
icantly reduces the complexity of investigating the contact interaction analysis in practice. It allows to defining the influence of the loading character and the material properties of the interacting bodies on the distribution of contact. Improved predictions of computationally obtained results could be helpful in improving the design studies. The selected results were expressed in graphs, contour plots and legend tables.
