  • Tensile Property Testing of Plastics

    Tensile Modulus of Elasticity. The tensile modulus is the ratio of stress to elastic strain in tension. A high tensile modulus means that the material is rigid - more stress is required to produce a given amnount of strain. In polymers, the tensile modulus and compressive modulus can be close or may vary widely.
