Elastic Properties and Applications

In the stress-strain behavior of a ductile material, what happens after the maximum stress the material can endure?

After the maximum stress (ultimate tensile strength), a ductile material experiences a decrease in stress with additional strain, leading to eventual fracture. As per NCERT, applying relevant law/formula with correct units and sign convention leads to The material begins to fracture. This satisfies dimensional consistency and physical conditions given, so option A is scientifically correct.

Stress, Strain and Hooke's Law

In the stress-strain behavior of a material, what occurs after the maximum stress point when the material is ductile?

For a ductile material, after the maximum stress point (ultimate tensile strength), the stress decreases with increasing strain as the material necks, leading to fracture. As per NCERT, applying relevant law/formula with correct units and sign convention leads to The stress decreases leading to fracture. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
