Sedin Technologies Lead Design Engineer Interview Questions and Answers

Ductile material is a type of material that can undergo significant plastic deformation before failure.

• Ductile materials can be stretched into wires without breaking.

• They exhibit large deformations under tensile stress.

• Examples include gold, copper, and aluminum.

Brittle material is a material that breaks or shatters easily without significant deformation.

• Brittle materials have low toughness and high stiffness.

• They exhibit little to no plastic deformation before fracturing.

• Examples include glass, ceramics, and some polymers.

Bulk Modulus is a measure of a substance's resistance to compression under pressure.

• Bulk Modulus is a measure of a substance's resistance to compression.

• It is defined as the ratio of the applied pressure to the resulting fractional decrease in volume.

• It is commonly used in materials science and engineering to characterize the compressibility of a material.

• Example: Rubber has a low bulk modulus, while diamond has a high
