    • Abstract
  • 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.
