Abstract
A two dimensional orthotropic thermoelastic finite element algorithm is developed herein, and it is used to evaluate the performance of a metal matrix composite (MMC) structural component provided by G.E. and Battelle Labs. The component consists of a monolithic fitting diffusion bonded onto a MMC laminate. Analyses performed with the finite element algorithm suggest that the bondline between the composite and fitting is the weakest portion of the structure for every combination of material properties and layup considered. It is also shown that residual stresses due to processing as well as three dimensional edge effects are significant and should be considered in further studies. The analysis also indicates the presence of a stress singularity at a sharp comer along the edge of the bondline. As a result. a design modification is proposed in order to eliminate the singularity, thereby improving the component design.
