  • Abstract The aim of this work is to present a new, improved model for porous ductile solids at high temperatures, for which viscous effects are important. The sound matrix is assumed to obey a simple Norton law without threshold. The voids are assumed to be and remain spheroidal so that their shape is characterized by a single parameter. The model makes an essential use of the notions of gauge surface and gauge function , which extend those of yield surface and yield function of classical… CONTINUE READING
