Shear strength refers to how well a member can withstand two equal forces acting in opposite directions.
Fatigue strength is the property of a material to resist various kinds of rapidly alternating stresses.For example rod or an axle undergoes complete reversal of stresses from tension to compression.Bending a piece of wire back and forth until it breaks is another example of fatigue strength.
Hardness is that property in steel which resists indentation or penetration.Hardness is usually expressed in terms of an indentation made by a special ball under a standard load,or the depth of a special indenter under a specific load.
Elasticity is the ability to spring back to original shape.Auto bumpers and all springs should have this quality.
Ductility is the ability to undergo permanent changes of shape without rupturing.Modern deep-formed auto bodies and fenders,and other stamped and formed products must have this property.
Toughness is the ability to absorb m
