Previous work has demonstrated the use of a penalty methodology for enhancing the use of cohesive-zone elements to simulate double. cantilever beam (DCB) and flexible-arm peeling problems, both involving elastic arm deformation. This approach is extended to the general case of inelastic peel arm deformations. Refinements to the original penalty selection methodology are included to account for the influence of plasticity in the peel arms. Accuracy of the method is demonstrated by comparing simulation results to experimental data of epoxy-bonded aluminum arms being peeled at different angles from a rigid substrate. This work addresses significant complexities in the analysis that arise due to the inelastic deformation of the aluminum peel arms. (C) 2007 DuPont. Published by Elsevier Ltd. All rights reserved.
