摘要
本文通过复合材料力学中的微分法和微观力学分析直接导出了泡沫塑料杨氏模量和泊松比所满足的微分方程组,并通过对方程组的讨论得到了泡沫塑料杨氏模量理论预测的近似公式。这些公式形式简单,与实验符合较好,便于工程应用。
The differential equations about Young's modulus and Poisson's ratio of foamed plastics are directly derived by differential scheme of composite mechanics and analyses of micromechanics. The approximate formulae for theoretical prediction of Young's modulus are obtained from the discussion of the equations, and expressed in simple forms. A good agreement with expermiental results has been reached. It is indicated that the formulae can be easily used in engineering.
