Abstract
The paper presents the compatibility relation of displacement, strain energy expression,
and the formulations of Finite Element Method in the transitional region for the improved damage
model of 2-D delamination[1]. The postbuckling behaviors of composite laminated plate with a
circular delamination are analyzed. Results show that the model mainly improves computational
results of energy release rates in the delamination front. The model should only be used in a narrow
region near the crack-tip and the normal Mindlin model in other regions. It leads to little increase in
the amount of computation, but significant improvement in the results.
