Boundary conditions:A quarter-section is modeled with the symmetry conditions 0 along 0 and 0 along 0. Loading:Within the hot-spot, thermal strain () = 1.0 × 10−3. Outside the hot-spot, thermal strain () = 0. Reference solutionThis is a test recommended by the National Agency for Finite Element Methods and Standards (U.K.): Test T1 from NAFEMS publication TNSB, Rev. 3, “The Standard NAFEMS Benchmarks,” October 1990. Target solution: at point D (outside the hot-spot) = 50.0 MPa. Results and discussionThe results are shown in the following table. The values enclosed in parentheses are percentage differences with respect to the reference solution.
*A comparison of the results for reduced-integration and full-integration elements indicates that the full-integration elements perform significantly better for problems with stress concentrations of this type. Input files
