Introduction
Thermal stress can cause many defects during
solidification processes of casting. Researchers mainly
adopt integrated FDM/FEM to simulate stress field.
From the mid-1960s, the FEM has been the dominant
numerical method in the field of solid mechanics,
people has decreased interest to the FDM applied to
this field.
we presented a FDM to build the discretizated
equilibrium equations in terms of displacements for
the stress simulation program development. The
program gained logical simulation results about
deformation and stress.
