Kharghani, N. and Guedes Soares, C. (2016), “Effect of uncertainty in the geometry and material properties on the post-buckling behavior of a composite laminate”, Maritime Technology and Engineering 3, Guedes Soares, C. & Santos T. A., (Eds.), Taylor & Francis Group, London, UK, pp. 497-503
Exact determination of material properties and fabricating composite laminates with a precise desired thickness presents considerable difficulties in experimental and numerical investigations. This paper, addresses the effect of uncertainty in the values of elasticity modulus and dimensions on the behavior of a laminate under buckling load using Response Surface and Monte Carlo methods. An analytical method is introduced to predict the composite plate behavior. Simply-supported and clamped boundary conditions are investigated. The results will demonstrate safe-fail domain, uncertainty propagation and sensitivity of the laminate behavior respect to the above-mentioned parameters.
