Compressive Behaviour of Pristine and Impacted Composite Laminates: Numerical Simulations and Experimental Studies

Krishna Lok Singh, Madhu K S, Mallikarjun R V

Abstract


To predict the compressive strength, various failure criteria studied in this article include are Tsai-Wu, Hill, Hoffman, Maximum Stress and Quadratic. The quadratic failure criterion has been implemented using PATRAN Command Language (PCL). Is observed that quadratic failure criterion provides least failure indices, employed for conservative design. The compressive strength of the pristine and impacted laminate computed using analytical experiment, and finite element analysis (Numerical) commercial packages. Experimental program employing both types of laminates (pristine and impacted) was conducted to demonstrate the accuracy of finite element analysis. A comparison of load deflection curves of experimental and numerical simulations considering both the linear and nonlinear regime shown.
