Abstract
In designing metal mold for casting, it is important to estimate the thermal stress generated in a mold. The analysis must take into account non-linearity of mold material, temperature dependence of material properties and thermal history.
In this paper, thermal stress of semi-infinite cylindrical metal mold was analyzed by a computer program following the finite element method taking the above conditions into consideration. The results revealed the influence of thickness and initial temperature on the thermal stress in mold in a short time range after pouring. The application of the results of the calculation to real situations was discussed.
