Modeling of delamination using a layerwise element with enhanced strains Academic Article uri icon


  • A layerwise finite element with enhanced strains is developed for the analysis of laminates with special emphasis on the study of delamination characteristics. An interface model using the penalty function method is developed to calculate strain energy release rates. Since the interface model provides the facility for the closure of delamination by a small amount, strain energy release rates were evaluated by actual crack closure and by virtual crack closure methods for a comparative study. A double cantilever plate problem is used to illustrate the accuracy of the computational approaches developed herein. 1998 Elsevier Ltd. All rights reserved.
