WebAccording to the Hooke’s law, the stress is proportional to the strain (in the elastic region), and the slope is Young’s modulus. Young’s modulus is equal to the longitudinal stress divided by the strain. Hardness of Low-carbon Steel – ASTM A36. Brinell hardness of low-carbon steel is approximately 120 MPa. WebA number of polymeric materials show properties in-between those of liquids and classical solids. These materials appear to be solid but under stress they show some continuous liquid-like deformation, that is, the deformation, even at low stress, is not reversible as it is the case for normal solids. The materials are often termed viscoelastic ...
