| Abstract: | NURBS is the most typical way for three dimensional numerical simulation of plastic deformation and its molding function is very powerful. We studied how to construct the equation of curves and surfaces with NURBS, how to generate mesh reasonably and how to interpolate and generate surfaces. At same time, a computer program to describe the space surface of the mold had been worked out with FORTRAN language. |
