The Effect of Different Behavior in Tension than in Compression on the Mechanical Response of Polymeric Materials

  • E. F. Rybicki

High polymers exhibit different stress-strain behavior in tension than in compression. The effect of this characteristic is examined in terms of three-point bending tests on polyethylene and polypropylene. A model to predict the experimentally obtained force-deflection curves is presented and used to illustrate the importance of including both tension and compression stress-strain data when these differ.
