| Abstract: | On the basis of the contour generating method of triangular grid, the generation of contour in the deformed quadrilateral shell element during finite element simulation of sheet forming processes is implemented fast and effectively.Each quadrilateral element is subdivided into four triangles by introduction of an imaginary node during the searching of contour points.As a result, the method avoids the complex algorithm of contour\|point tracking, making the programming easier. |
