| Abstract: | This study is a fundamental examination of the theoretical hypothesis that mechanical work is a multivalued potential function which characterizes the deformation and fracture behavior of inelastic materials during damage growth processes. Experimental data from fiber-reinforced plastic laminates subjected to axial and torsional deformation are analyzed for the existence of a work potential. A work potential-based method is employed to analyze data from proportional deformation tests and make predictions of load response. Good agreement is obtained between theory and experiment. Data from nonproportional deformation tests are then evaluated for displacement-path independence of work and load response. Domains of path independence are found from specimens strained well into the range of nonlinear in elastic behavior. Thus, the results of these experimental studies are consistent with the existence of a work potential. Work potential theory and experimental results are then used to determine critical energy release rates for mixed mode delamination of laminates subjected to axial and torsional deformations. |
