ABSTRACT

In this work thermal loading is introduced to the J-Integral calculation using FEM. Study the
effect of thermal loadings include temperature difference, convection heat transfer coefficient,
temperature of fluid, and thermal conductivity on stresses values and J-integral . three Programs
have been developed , first program is to evaluate temperature distributions in (conduction,
convection), while the second program is to compute thermal loading stresses and another
loading conditions, third program is to evaluate the J-Integral of opening mode (Mode I) under
effect of thermal and mechanical boundary conditions is introduced. so the comparison of the
result depends on the validation of the programs developed and the Extrapolation Methods. 

Keywords: J-integral , finite element , stress , displacement.
