Finite Eelement Simulation of Flexible Low-Density Polymer Foam During Moulding Process
In this paper,tiie large compressive deformation of low-density polymer foam is simulated by modeling a regular dodecahedron cell unit.The effects of slrut tiiickness,cell size,Youngs modulus and Poissons ratio on tiie compressive mechanical behavior of foam are investigated.By tiie use of a factorial design,The results indicate tiiat tiie strut thickness has the greatest effect on the maximum reaction force with positive non-linearity.Cell size ranks second in negative non-linear effect on the response while Youngs modulus ranks tiiird in positive linear effects.Moreover,the effect of tiie Poissons ratio plays only a small role on the response.This study demonstrates tiiat ideally,cell modeling with tiie properties of flexible open-cell foam material,followed by FE simulation,is an effective approach to understanding tiie mechanical behavior of foam during moulding process.
