DRAWING METHODS OF THREE DIMENSIONAL SPACE CONTOUR AND INTERNAL FORCE PICTURES

This paper is concerned with the drawing methods of three dimensional space contour and internal force graph based on the results of three dimensional FEM. According to the character of three dimensional FEM,the paper presents the automatic drawing program for three dimensional contour with multiple result closed curve and gives the iterative computation formula for local coordinates of three dimensional finite element. These methods can improve the three dimensional effect and have clear concept and less calculation.
