Question

Stress versus strain graph for a material is shown in figure. In graph a represents proportional limit, b represents elastic limit and d represents breaking point. If large deformation takes place between elastic limit and breaking point, then the material is called

• A. Brittle
• B. Ductile
• C. Initially Brittle and then ductile
• D. None of these

Answer 1

The correct option is A Brittle

$\begin{array}{c}\text{If large deformation takes place between elastic limit}\\ \text{and breaking point then the material is brittle.}\\ \text{For ductile materials the deformation will be less}\end{array}$
