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
Rocky shore coast in France and the Exxon Valdez spill in Prince William Sound, Alaska, USA. Garbage such as plastics and metals being left behind by people is also a problem among many rocky coastlines that attract tourists. Rocky shore A rocky shore is an intertidal area of seacoasts where solid rock predominates. Rocky shores are biologically rich environments, and are a useful "natural laboratory" for studying intertidal ecology and other biological processes. Due to their high accessibility, they have been well studied for a long time and their species are well known. There are a large number of factors that favour
