SpletT he deformation behaviour of elastomers is often characterised by specifying the Shore A hardness [1], and less often via the modulus of elasticity.The reason for this is probably because measuring the modulus of elasticity of elastomers by means of the usual methods is not very simple. This fact must be viewed in light of the practical interest to know the … Splet19. jun. 1980 · They found an increase in the Young's modulus mostly from the age of 45, with values generally greater in women. We also found a larger Young's modUlus in women in the age groups 0-10, 20-30, 40-50, and above 70. However, this difference was not statistically significant. Alexander and Cook [1], using an apparatus similar to ours, found …
