Abstract:

Article Preview

A trimming algorithm is presented for trimming process of refined meshes in sheet metal forming simulation. Firstly, trimming line is pretreated to guarantee it smooth enough for trimming process. Secondly, the elements around the trimming line are found and refined to the highest adaptive level. Thirdly, the intersection points between trimming line segment and the element edge can be obtained using an Advancing Inciting and Adjustment method. Then new number is distributed to nodes of elements on one side of trimming line so that the meshes can be divided into several parts by the trimming line. Finally physical quantities of the remained elements are inherited from the original elements. At last the validity, practicability and speediness of the algorithm are verified with a numerical experiment. And the algorithm is integrated into a sheet metal forming simulation program, FASTAMP.
