Difference between Stiffness (K) and Modulus of Elasticity (E)?
In Solid Mechanics, We can relate these K=AE/L. I am confused in these. Both resist deformations when load is applied on it. Is K constant like E is constant. Another thing which is

How do I plot the relation between hardness of a material and compressive strain knowing the stress-strain curve and indentation size in Brinell''s hardness test
The size, shape, layout, and many other properties of these grains has a considerable impact on the macro-scale properties of the metal, e.g it''s toughness, rigidness, tensile strength,
Can someone help me understand durometer and shore hardness testing with relation to rubber hardness? My understanding is durometer measures hardness, shore is a different type of
for this question: "What is the difference between strength, hardness and toughness in materials?" i have searched and have found these following definitions Strength refers to resistance to
Given similar strength and hardness spec, materials that work-harden can be much worse to work with. If milling or drilling, some materials form nasty chips compared to others. Some
Can some please explain why is the elastic modulus of aluminium and work hardened aluminium the same? Is it only the same for pure metals?
I would be very surprised if I found out that the standard demands a specific steel. In any case, the steels that can be used for a 12.9 bold should not exhibit any significant differences in
The effects of heating-quenching a metal is explained below Transformation hardening is the heat-quench-tempering heat treatment cycle addressed earlier in this article. It''s used to adjust
The steel tire could easily be any hardness you want. It would be poor judgement to mess with the rolling element bearing hardness. The heat-treatment has been developed over decades.
