Abstract

Base on CATIA 3D,evaluate the flattening of surfaces with gaussian curvature,collect the information of plies,and then,analyse the producibility of single surface in CATIA composites model,calculate the max gaussian curvature of surface notes with finite element analyse,carve up the surface according the max gaussian curvature.Finally,a meshed surface with several areas is used to flatten the developable surfaces.
