The 3-D finite element analysis program considering the coupling of heat conduction, damage evolution and liquid metal embrittlement has been developed in order to solve thermal damage and liquid metal embrittlement problems. The developed program has been applied to the evaluation of damage grenerated by the effect such as zinc-embrittlement in hot-dip galvanization. The heat conductivity considering the influence of damage is applied to heat conduction analysis and the damage analysis is conducted by the finite element program using the constitutive equation based on Lemaitre's theory. Numerical studies for the damage evolution in thick cylinders under high temperature have been done to show the validity of the coupling of heat conduction, damage evolution and the effect of liquid metal embrittlement.
