Shore durometer is in MPa. Another linear relation between the ASTM D2240 hardness value and material elastic modulus has the form where formula_14 is the ASTM D2240 type A hardness, formula_11 is the ASTM D2240 type D hardness, and formula_2 is the Young's modulus in MPa. Shore durometer The Shore durometer is a device for measuring the hardness of a material, typically of polymers, elastomers, and rubbers.. Higher numbers on the scale indicate a greater resistance to indentation and thus harder materials. Lower numbers indicate less resistance and softer materials. The term is also used to describe a material‘s rating on the
South Shore, Chicago the 1920s generated not only a large increase in the area's population, but also greater diversity among its residents and in housing stock. Between 1920 and 1930 the population of South Shore jumped from 31,832 to 78,755.
