Modeling and Analysis of Orthotropic Plate with Circular Cutout and Adhesive Bonded Patch

Abstract

The purpose of this study was to investigate a modeling technique to simply and adequately model an adhesive bonded patch on an orthotropic plate. This report is limited to linear material behavior. This thesis is also the basis for further work into nonlinear material range and three-dimensional stress states. To further advance aerospace battle damage repair techniques for composite repairs, a finite element model of an orthotropic plate with a hole and patch was constructed to investigate the accuracy of such a model. The fundamental problem in this model is the development of a simple and accurate method of modeling the bond between patch and plate. MSC/NASTRAN spring elements were used to this end. The spring elements provided an elastic method of load transfer between the plate and patch.
