Q292

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
Answer

Answer: Option D

Solution

Answer: Option D
Solution:
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
