List of top Metallurgical Engineering Questions on Fracture Mechanics asked in TS PGECET

Which method permits point-by-point calculation of stress but is limited to plane-strain conditions only?

According to Irwin, the local stresses near a crack depend on the product of

The law which states that fracture occurs when the resolved normal stress on a plane reaches a critical value is

Brittle fractures occur in a trans granular manner. If the grain boundaries contain a film of brittle constituent, the fracture will occur

The analytical treatment of ductile fracture using a model of cylindrical holes with initial radius (b) and average spacing (L) was proposed by

Consider the following Assertion (A): A notch increases the tendency for brittle fracture in a material. Reason (R): A notch produces high local stresses, introduces a triaxial tensile state of stress, causes local strain hardening, cracking and magnifies the local strain rate.

The sensitivity of fracture of brittle solids to surface conditions is termed as the

Blue powder is the byproduct of Zinc extractions and it contains mainly:
