A correlation study has been made to evaluate the effectiveness of finite-element modelling for the stress analysis of composite-material laminates. The specific problems studied are: a boron—epoxy composite laminate with a circular hole under axial tension; a boron—epoxy composite laminate with an elliptical opening under axial tension; a glass-fibre-reinforced plastic plate subjected to line load; and a glass-fibre-reinforced plastic annular disc under diametrical compression. Correlations of finite-element predictions are made with analytical solutions and experimental data. The study has demonstrated the accuracy of finite-element modelling employing a quadratic strain traingular (QST) finite-element for the stress analysis of composite-material laminates.

Knowledge of the complex deformation behavior in the anisotropic materials is one of essential issues in materials science and it is crucial for the applications of a given material. In this study, mechanical response of Fe3(wt.%)Si single crystal to nanoindentation with spherical indenter was investigated. Hardness and indentation Young´s modulus were determined experimentally and by finite element modelling. Observed pop-in phenomenon, shape of the residual imprints and origin of the slip lines were explained on the basis of resolved shear stress computed by finite element model.
