Analytical, FEM-numerical and experimental studies of bending of a sandwich plate-strip with metal foam core

Pojazdy Szynowe, 2020
The subject of the study is a sandwich plate-strip subjected to a four-point load. An analytical model of the strip was developed, taking into account the classical zig-zag theory, namely the broken line hypothesis.

A further discussion on the effective thermal conductivity of metal foam: An improved model [PDF]

, 2015
In this study, we explain the causes and effects of the geometrical impossible result encountered in the widely adopted tetrakaidecahedron model (Boomsma and Poulikakos, 2001; Dai et al., 2010) for the effective thermal conductivities (ETCs) of metal ...
