Stress is the force per cross-sectional area that a material withstands. Strain is the percent change in the length of the material. The stress-strain curve is the simplest way to describe the mechanical properties of the material. dvds right to askWebIn polymers, there are covalent bonds between the atoms of the polymer, but the polymeric macromolecules (or chains) are kept together by Van der Waals forces. Of all the four types of bonds, Van der Waals is the weakest. For this reason, polymers are very elastic (e.g., a rubber band), can be easily melted, and have low strength. dutch bazaar torontoWebAug 23, 2011 · The creep modulus values tell us something about how the material behaves if a constant stress is maintained.
