摘要:Abstract(#br)Low-density closed-cell aluminum foam is promising to be used as load-bearing and thermal insulation components. It is necessary to systematically study its thermal expansion performance. In this work, linear thermal expansion coefficient (LTEC) of the closed-ce...

摘要:Abstract(#br)Cellular materials under high-velocity impact have highly localized deformation with the cells layer-wise collapse, which is usually characterized by the propagation of shock wave. Researches have shown that the shock wave speed is strongly dependent on the impa...

摘要:Abstract(#br)Quasi-static perforation and low-velocity impact tests at different temperatures were carried out for sandwich panels with aluminum face sheets and a closed-cell aluminum foam core. The deformation and failure behaviors, load carrying capacity and energy absorption c...

摘要:Abstract(#br)The ellipticity involved in the Deshpande-Fleck foam model describing the constitutive behaviour of cellular materials was usually considered to be constant, but some very different values were suggested in the literature. A cell-based finite element model of cl...
