Abstract

As one of analytical problems of thermal stresses with a moving boundary, we analyzed thermal deformations and thermal stresses caused by a phase transformation. We assumed that a cooled end surface of a semi-infinite solid cylinder, which is kept at a constant temperature, yields the phase transformation with respect to the axial direction; then as a result, the solid cylinder could be seprated into two dissimilar solid phases with thermally and thermoelastically different material properties by a moving interface. In the analytical developments, we adopted Neumann's solution for one-dimensional temperature distribution, and then we analyzed the axisymmetric thermoelastic field with aid of the thermoelastic displacement potential function and Love's displacement function. As an illustration, numerical calculations are carried out for Martensite Transformation, and the influence of the latent heat on the temperature and thermoelastic fields were examined precisely.
