12 Questions
Define ductility in materials.
Ductility is the ability of the material to undergo large inelastic deformation without fracture.
What is toughness in materials?
Toughness is the ability of the material to absorb energy and is characterized by the area under the stress-strain curve.
Explain weldability in the context of steel.
Weldability is the ability of steel to be welded without changing its basic mechanical properties.
What is Poisson's ratio?
Poisson's ratio is the ratio of the transverse strain to the longitudinal strain.
Define shear modulus.
Shear modulus is the ratio of the shearing stress to shearing strain during initial elastic behavior.
What does Poisson's ratio represent?
Ratio of transverse strain to longitudinal strain
