Choose the correct option(a) post ultimate strain softening in enginee

1.	Choose the correct option(a) post ultimate strain softening in engineering stress strain curve is present in true stress strain curve(b) post ultimate strain softening in true stress strain curve is absent in engineeringstress strain curve(c) post ultimate strain softening in true stress strain curve is present(d) post ultimate strain softening in engineering stress strain curve is absent in true stress strain curveThis question was addressed to me during an interview.This interesting question is from Behavior and Design Strength of Tension Members topic in chapter Design of Tension Members of Design of Steel Structures
Answer» Right choice is (d) post ultimate strain SOFTENING in engineering stress strain curve is ABSENT in true stress strain curve To EXPLAIN I would say: The post ultimate strain softening in engineering stress strain curve CAUSED by necking of cross section is absent in true stress strain curve as engineering stress strain curve are based on true DIMENSIONS of specimen and true stress strain curve are based on actual cross sectional area of specimen.
