Composites materials are needed because of the widely used in structures and designs. In this work, the stress analysis of two-dimensional bilayer composite materials has a different passion ratio have studied. The materials under consideration are assumed to be perfectly bonded together. Finite difference method is used for the solution of two-dimensional elastic problems. In each layer of the composite, the mechanical properties are isotropic. The results are observed that the results agree well within the acceptable limit, which also confirms the reliability of the finite difference method. Changing in Poisson’s ratio in any layer has significant effects on the results of all layers of the bilayer composite. Due to the mathematical expressions of stresses and displacements for two-dimensional elastic problems, the study of the effects of Poisson’s ratio has a significant influence.

The most effective way of determining the whole billet temperature field is to use a simulation model. Large amount of calculation as well as computational time is consumed to employ two-dimensional finite difference method since the heating process is extremely complex, then it’s necessary to simplify the calculation process. In this paper, a simplified method in one-dimension format was presented to calculate two-dimensional heat conduction equations of heating slab. The billet simulated was placed in a changeable thermal flux boundary environment, in which the thermal flux was proportional to fourth power of temperature. During the heating process, the changeable parameters were taken into account: i. e different billet dimensions, different billet thermal conduction, different specific heat, etc. The comparision between results of two-dimensional finite difference method and the simplified method verified that the simplified method can satisfy accuracy requirement as well as calculation time saving, which enable the simplified method online using.
