abstract = {To investigate the compressive effects through microscopic features of flexible low-density open-cell PU
foam during moulding process, FE simulation of deformation based on a regular dodecahedron cell unit
with uniaxial compression behavior is undertaken to examine the mechanical properties of the vertical
loading direction, and to facilitate the incorporation of solid PU material properties and variations in
cell geometry. By the use of a factorial design, the mean strut thickness of solid struts has a positive
non-linear effect on the maximum reaction force as compared against cell size with a negative non-linear
effect. The Young's modulus of solid polymers had a positive linear effect on the response while the
Poisson's ratio had the least impact on the response. Development of a simplified cell unit can model
the behavior of open-cell PU foam under uniaxial compression which is an effective way to understand
the mechanical behavior of foam during moulding process.},
