Course objectives:
|
The course is focused on mechanical properties of composite materials. The basic terms for elastic materials are introduced, such as stress and strain, Hooke's Law and classification of anisotropic materials. The focus is given to unidirectional composites - laminate. Relations for off-axis stiffness and compliance and off-axis elasticity constants are derived. The summary of macromechanical failure criteria for unidirectional composites is given. Special attention is paid to analysis of laminates. It is shown how the laminate lay-up influences the mechanical properties of the laminate, stresses caused by temperature change or by moisture absorption. Analysis of thin-walled tubes prepared by filament winding is presented. The laboratory classes will include the solution both analytically and numerically and using modern computational methods. Portion of the classes will take place in computational labs where numerical simulations of mechanical behaviour of composite materials will be performed.
