【Abstract】 A method of displaying the curves with the same stress values or thesame displacement values in the post processing of finite element analysis is presented, as well asits algorithm and the data structure. Then, applying the algorithm for the stress field with triangular element surfaces to the case of the quadrilateral element surfaces, the unified algorithm to display the curve with equal stress values and the displacement ones for the surfaces of the triangular and quadrilateral elements is given.更多还原
