Abstract

This paper presents an analytical approach that combines the modified shear-lag model and the Monte-Carlo simulation technique to simulate the fracture behavior, including the failure process and energy release rate, for unidirectional fiber-reinforced composites at different temperatures. The simulated results, based on the unidirectional carbon fiber-reinforced polymeric (CFRP) composites, were compared with existing experimental observation and measurement. A good agreement between the simulation and experiment was obtained, and the critical energy release rate of the unidirectional CFRP composite was found to increase with the decrease of the temperature. This increase is primarily due to the temperature-dependence of the composite constituents rather than the residual stresses induced due to the change in temperature.
