On the basis of structured unified hardening model (structured UH model) considering soil collapse, time effect is take into account, and an elastic-viscous-plastic extended. In presented model, moving normal compression line (MNCL) extended to a instant (MINCL) for simulating both structure effect. Then instance plastic strains irrespective are calculated by referring MINCL, due traditional li...

With the development of plastic surgery techniques, computer aided approach has become a significant method in medical plastic surgery. In order to solve effects on surgical results made by the surface of a wound in craniofacial cosmetic surgery, accurate preoperative preparation is usually required for the surgery. This paper summarizes the application of computer aided technology in craniofac...
