Question

Which one of the following pairs of tests has been developed to evaluate the fracture resistance of engineering materials, subjected to dynamic loads or impacts?
1. Tension impacts and bending impacts
2. Tensile test and Brinell hardness test
3. Vickers hardness test and Tensile test
4. Scleroscope test and file test

Answer 1

Correct Answer - Option 1 : Tension impacts and bending impacts

To evaluate toughness or fracture resistance of a material which are subjected to a rapidly applied load or impact, basically two types of tests are applied.

(i) Bending impacts (Charpy test, Izod test)

(ii) Tension impacts (Eliminates the use of notched specimen)
