Abstract: A new constitutive model for transfer of interfacial tractions along rough cracks in strain softening composites is presented. The model relates the normal and shearing stresses on the rough crack to the corresponding displacements in terms of the interface strength, contact areas, the contact angle, and the crack closing pressure. The performance of the constitutive model was evaluated by predicting experimental results. The comparison between predicted and experimental results appear to be very satisfactory.
