01 The rubber like elastic rubber is different from the elastic energy represented by the longitudinal elastic coefficient (Young's modulus). It refers to the so-called "rubber elasticity" that can be restored even for hundreds of percent deformation on the basis of the entropy elasticity generated by the contraction and spring off of the molecular lock. 02 Embodiment rubber

For all kinds of articles in life, our feelings about them are intuitive, such as the concepts of hardness, elasticity, toughness, brittleness, etc. This information obtained through intuitive feeling and perception is generally called qualitative judgment. Qualitative judgment is usually vague, imprecise and not conducive to comparison. Just as we know that iron is hard and steel is hard, which one is harder, except for the two
