The presence of residual stresses in a component can prevent failure of the casting component.

The presence of residual stresses in a component can prevent failure of the casting component. Correct Answer True

Residual stresses may play an important role in explaining or preventing failure of a component at times. For example, shot peening of component to induce surface compressive stresses, in which residual stresses prevent failure and also improves the fatigue life of the component. But the internal or residual stresses should be kept balanced in the casting component.

2. Failure to put the material evidence amounts to a serious irregularity which can not be cured and vitiates the trial, if it has prejudiced the accused.
3. Failure to put the material evidence is not considered to services & is curable if infact no failure of justice has occasioned to the accused.
