Abstract

Simple analytical models are applied in order to explore the relationship between notched and unnotched strength of CFRP laminates under a range of test conditions – cold dry, room temperature, and hot/wet. The methodology adopted makes use of a stress-based approach for predicting damage growth, in conjunction with a fracture mechanics model for ultimate failure/fracture. Applying the resulting model to the experimental data enables the fracture toughness of the test material to be determined as a function of test condition. The model is also able to demonstrate that at any particular test condition, a given variability in unnotched strength data translates into a smaller variability in the associated notched strength data.
