abstract porous materials are commonly found in nature and as industrial materials such as wood, carbon, foams, ceramics and bricks. in order to use them effectively, their mechanical properties must be understood in relation to their micro-structures. foam made from non-flammable metal will remain non-flammable and the foam is generally recyclable back to its base material. this research work ...
A straightforward criterion to determine the limp model validity for porous materials is addressed here. The limp model is an "equivalent fluid" model which gives a better description of the porous behavior than the well known "rigid frame" model. It is derived from the poroelastic Biot model assuming that the frame has no bulk stiffness. A criterion is proposed to identify the porous materials...
