A composite damage model based on continuum damage mechanics (CDMs) is proposed for the progressive damage analysis of a composite structure. The damage progressive law that considers the Weibull distribution of the composite strength was employed in the damage model. The nonlinear shear behavior of the composites was also considered. Also, a simple model that considers the irreversible strain due...
In this study, experimental tests and an analytical approach are conducted to verify the size effect on the fiber strength of a composite pressure vessel. As an analytical method, the Weibull weakest link model and the sequential multi-step failure model are considered and mutually compared. In the case of carbon fiber tensile strength, there is no large difference between the analytical methods for...
