Idac Solutions FEA Engineer Interview Questions and Answers

Mild steel has a gradual yield point and high ductility, while aluminum has a sharp yield point and low ductility.

• Mild steel has a gradual yield point, while aluminum has a sharp yield point.

• Mild steel has high ductility, while aluminum has low ductility.

• Mild steel can withstand more stress before breaking than aluminum.

• Aluminum is lighter than mild steel and has better corrosion resistance.

Stress is the force applied to an object, while strain is the resulting deformation or change in shape.

• Stress is measured in units of force per unit area, such as pounds per square inch (psi) or newtons per square meter (N/m²).

• Strain is measured as a ratio of the change in length or shape of an object to its original length or shape.

• Stress and strain are related through a material's elasticity, which is the ability of ...read more
