The loss of strength in compression with simultaneous gain in strength in tension due to overloading is known as

A Hysteresis
B Creep
C Visco elasticity
D Boeschinger effect

Correct Answer: Boeschinger effect

The Bauschinger effect refers to a property of materials where the material's stress/strain characteristics change as a result of the microscopic stress distribution of the material.
For example, an increase in tensile yield strength occurs at the expense of compressive yield strength
