| Popis: | 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. |
