Alizadeh, F., Garbatov, Y. e Guedes Soares, C. (2017), “Numerical investigation of pre-damaged composite plates subjected to compressive uniaxial load”, Progress in the Analysis and Design of Marine Structures, Guedes Soares, C. & Garbatov Y. (Eds.), Taylor & Francis Group, London, UK, pp. 841-848

Pre-damaged composite plates subjected to a compressive uniaxial load are studied. The effect of a number of damaged layers and the spread of the damaged central area on the ultimate strength based on the nonlinear finite element method has been studied employing the ANSYS commercial software. The ultimate strength of the plates with different degree of damaged layers made of an orthotropic composite laminate (E-glass/ vinylester) is estimated using the Tsai-Wu failure criteria. The numerical estimation of the longitudinal and transverse deflection of undamaged plates is compared to the experimental results. The effect of the surface roughness on the ultimate strength is also investigated and several conclusions are derived.
