The behaviour of a metal specimen, which when plastically strained in tension reduces its yield stress in compression and vice versa; is termed as the_______________?
Correct answer: C. Bauschinger effect
- A. Work hardening
- B. Creeping effect
- C. Bauschinger effect
- D. Stress recovery effect
Explanation
The Bauschinger effect occurs when prior plastic deformation in one direction lowers the yield stress during reverse loading. Work hardening, in contrast, generally raises resistance to further deformation in the same direction.
