Bookmark or Share- Difference between Stiffness (K) and Modulus of Elasticity (E)?"Hardness" - Hardness (antonym: softness) is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion. In general, different materials differ in their hardness. Its usage is limited to the cases stated above.
- At what temperature do I risk altering the structure of steel?The second consideration is the tempering temperature. This only applies to steels which have been heat treated, generally cutting tools, dies, springs and certain other very high strength/hardness parts. The tempering range can vary between 180 and 300 C or up to 600C for high speed steels.
- Shore durometer type D to brinells - Engineering Stack ExchangeI saw a video where a person was measuring hardness of a material with Shore durometer type D and was comparing it to steel. The screen on durometer showed 96.5 HD and I was just wondering, how much
- automotive engineering - What is the significance of brittle materials ..."Hardness is the question of how difficult it is to make an impression/indention on a substance. Brittleness is the question of how easy it is to break. For example, Granite is a stone which is very hard but not brittle--it is hard to carve and also hard to break. A plank of wood is not as hard as stone but is not very brittle.
- Strength vs. Hardness vs. Toughness - Engineering Stack ExchangeHardness is the measure of a material resistance to scratching, like it's hard to drill a hole into, or hard to sand. Or diamond that can cut many surfaces but is hard to cut. Toughness is the ability of material to resist cracking or breaking under stress. Strength is the ability of material to withstand great tension or compression or other ...
