摘要：

The numerical aspects of a micromechanical model for a viscoelastic cohesive zone are discussed herein. The cohesive forces encountered in the region ahead of a crack tip are represented by a damage dependent traction-displacement law which is both history dependent as well as internal variable-type. An incrementalized form of this traction-displacement law has been integrated numerically, and an example problem has been solved to demonstrate the efficacy of the model.
