Abstract:

New solutions are obtained herein for the dynamic mechanical response of a one-dimensional finite elastic strip that is cohesively bonded to a rigid substrate. Analytic solutions are obtained for a variety of cohesive zone constitutive behaviors including linear elastic, viscous, viscoelastic, and cohesive zones with evolving internal damage. Results are compared to numerically obtained predictions using the explicit finite element code DYNA3D 1. It is shown that the analytic and numerical results are essentially indistinguishable, and validate the implementation of the damage dependent cohesive zone model 2 into DYNA3D.
