Abstract

Composite materials have established a predominant status in engineering structures. However, their understanding is not as easily accessible as other conventional materials i.e., metals or noncrystalline solids. That is why computer-based models are needed to perform the intensive and repetitive calculations that are usually associated with calculating composites properties. The present thesis is concerned with developing a simple and precise computer code that accounts for: calculating and demonstrating the stress-strain distribution for the laminate structures, determining the load carrying capacity, performing failure analysis of a composite laminate, and predicting crack propagation parameters once such flaw is initiated in the unidirectional fiber laminated composites. It allows us to design and analyze laminated structures with different stacking sequence and appreciate their applications in an interactive manner with preliminary computer knowledge only.
In order to validate the proposed analysis of fiber reinforced composite materials, the output of our computer code was successfully compared with recently published experimental results. Also, a set of correlating experiments were designed to verify many of the code’s results and the outputs were found to agree well within the expected experimental tolerance.
