N2  - Fiber-reinforced polymer composites (FRPCs) are increasingly being utilized in a wide variety of industrial sectors ; such as aerospace , automotive , biomedical , civil infrastructure , renewable energy and marine A detailed awareness of the mechanical properties of these composites is extremely important for their appropriate design and optimization Experimental determination of these properties like strength and modulus is restrictively extravagant , as there are unlimited significant factors that contribute to the increase in experimental cost including materials , tooling , processing , machining , testing and many others A standout amongst the most significant , however most challenging endeavors in composites design and analysis is modeling material and structural failure More importantly , understanding how and when a structure fails is crucial to determining how its design could be optimized , and whether it would meet its requirements In this thesis , progressive failure analysis was performed on open-hole (O-Hole) FRPCs under tensile loading The effect of existence of central hole , varying fabric orientation (0, 45, or 90°]), and utilizing different types of fabrics (unidirectional or woven) on the behavior of FRPCs (load , stiffness , and progressive failure) were investigated The commercial finite element platform ABAQUS/Standard V6.12 was used for the finite element simulations , and the commercial plug-in for ABAQUS , Autodesk Simulation Composite Analysis was employed This plug-in utilizes the concept of Multi-Continuum Theory (MCT) to efficiently model progressive failure by extracting the average constituent (fibers and matrix) stresses and strains from the corresponding composite ones and applying the appropriate physics to the constituent materials individually in order to predict composite structure failure response The woven model is validated according to a pre-published experimental work It was found that the numerical model is in good correlation with the experimental work
