  shape sensitivity analysis
     In this paper, a systematic method based on shape sensitivity analysis is proposed to optimize the blank shape in deep drawing of truck headlamp reflector. The optimization calculation is programmed. By using a well known dynamic explicit analysis code LS DYNA3D, the deformation of the assuming initial blank and the offset blank are calculated and the shape sensitivity of the outmost node can be obtained numerically, then the initial blank is modified and the deformation process is analyzed again.
