A laminate which is composed of 4 layers of unidirectional glass fibres with stacking sequence of (0°,900,90°,0º) and the elastic modulus of the lamina in the 0 degree orientation is 50 GPa while in the 90 degree orientation is 10 GPa, where the O degree orientation is along the main direction of the laminate. Similarly, the tensile strength and compressive strength of the lamina in the 0 degree orientation are 400 MPa and 200 MPa respectively while that of the 90 degree orientation are 80 MPa and 50 MPa, respectively. Each layer has a thickness of 2.0 mm. If the laminate is 15 mm wide, has a length of 80 mm and loaded at midspan under 3-point loading, which lamina will most likely to fail first and at what level of applied load?
