Plastic deformation in zinc and copper, the metals US pennies are made from (post and pre 1982, respectively), is defined by two properties called the Compressive Yield Strength and the Strain Hardening Exponent of the metal. Yield Strength is a measurement of the pressure required to cause the metal to flow, rather than bend like a spring.
