Indian Institute of Technology Gandhinagar PHD Student Interview Questions and Answers

The strain in x direction cannot be determined without additional information.

• The 3D stress block only provides information about the stress components in the x, y, and z directions.

• To determine the strain in a specific direction, additional information such as the material's elastic modulus and Poisson's ratio is needed.

• The strain can be calculated using the formula: strain = stress / (elastic modulus * (1 + Poisson's

Throat thickness of steel members as per IS Code varies based on the size of the member.

• Throat thickness is the minimum thickness of the weld at the root of the joint.

• As per IS 800:2007, the throat thickness of fillet welds should be at least 0.7 times the size of the smaller member being joined.

• For example, if the size of the smaller member is 10 mm, the throat thickness of the fillet weld should be at least 7 mm.
