Multiscale Modeling of Tensile Failure in Fiber-Reinforced Composites
Fiber-reinforced composites can be engineered to exhibit high strength, high stiffness, and high toughness, and are, thus, attractive alternatives to monolithic polymer, metals, and ceramics in structural applications. To engineer the material for high performance, the relationship between material microstructure and its properties must be established to accurately predict the deformation and failure. Such a relationship between underlying constituent material properties and composite performance can also aid selection and/or optimization of new composite systems. Successful models can yield predictive insight into the origins of damage tolerance, size scaling, and reliability of existing composite systems and can be extended to investigate damage and failure under more complex loading and environmental conditions, such as fatigue and stress rupture.
