Question

Arrange the regions of engineering stress-strain curve in order from right to left as in graph

(a) strain softening region, strain hardening region, yield plateau, linear elastic region

(b) strain hardening region, strain softening region, linear elastic region, yield plateau

(c) strain softening region, yield plateau, linear elastic region, strain hardening region

(d) strain hardening region, linear elastic region, yield plateau, strain softening region

The question was posed to me in my homework.

My question is based upon Behavior and Design Strength of Tension Members in portion Design of Tension Members of Design of Steel Structures

Answer 1

Right choice is (a) strain softening region, strain hardening region, yield plateau, linear elastic region

Best explanation: The engineering stress-strain curve is typically represented by four regions : linear elastic region, yield plateau, strain hardening region, strain softening (unloading)region.
