The
ability of a tool material to resist shock or impact forces is known as:
Wear
resistance
Toughness
Red hardness
Machinability
Toughness
●Toughness
is defined as the ability of the solid material to absorb energy until fracture
occurs. This property is desirable in parts subjected to shock and impact
tools. So, it is the ability of a tool material to resist shock or impact
forces.
●Toughness
is an important consideration for metal forming processes (Forging, bending,
sheet metal operations etc.). Unit of toughness
Hence, the correct option is (B).
&Key Points:-
●Modulus
of resilience is area below engineering stress-strain curve upto elastic point.
●Modulus
of toughness is total area below engineering stress-strain curve.
