Analytical and Numerical Analyses for Two-Dimensional Stress Transfer

Both analytical modeling and numerical simulations were performed to analyze the stress transfer in platelet-reinforced composites in a two-dimensional sense. In the two-dimensional model, an embedded elongate plate bonded to a matrix along its length direction was considered. The system was subjected to both tensile loading parallel to the plate length direction and residual thermal stresses. The ends of the plate can be debonded from or bonded to the matrix during loading, and both cases were considered in the analysis. Good agreement was obtained between the present analytical and numerical solutions. However, compared to the solutions for the debonded-ends case, the solutions for the bonded-ends case were more accurately predicted by the present analytical model.
