摘要
本文通过数值法研究了胞体椭球比对材料模量及泊松比的影响；在单向受力情况下，研究了变形对材料孔隙度、椭球比、杨氏模量和泊松比等材料参数的影响．
On the basis of the differential equations of Young's modulus and Poisson's ratio for foam plastics with ellipsoid cells, the effects of cell aspect ratio on Young's modulus and poisson's ratio of foam plastics are investigated by the numerical method. In addition, under uniaxisl stress,the effects of deformation on the porosity, aspect ratio. Young's modulus and Poisson's ratio of foam plastics are also investisated at the same time.
