it indicates the maximum amount of strain-energy the material can absorb just before it fractures (ability to absorb energy in plastic range)
Modulus of toughness
Modulus of Resilience
Modulus of Elasticity
Modulus of Rupture
Represents the largest amount of internal strain energy per unit volume the material can absorb without causing any permanent damage to the material (ability to absorb energy in the elastic range)

Modulus of Resilience
Modulus of Elasticity
Modulus of Rupture
Refers to the property of a material which makes it return to its original dimension when the load is removed.
Ductility
Stiffness
Elasticity
Hardness
Refers to the ability of a material to deform in the plastic range without breaking
Ductility
Elasticity
Hardness
Stiffness
Ability to resist a deformation within the linear range. Inverse of this is flexibility
Stiffness

When a material has to support a load for a very long period of time, it may continue to deform until a sudden fracture occurs or its usefulness is impaired. This time dependent permanent deformation is known as _____
Yielding
Buckling
Creep
Fatigue
When a material is subjected to repeated cycles of stress or strain, it causes its structure to breakdown, ultimately leading to fracture. This behavior is called
Yielding
Buckling
Creep
Fatigue
lateral deflection that occurs when long slender members are subjected to an axial compressive force.
Yielding
Buckling
Creep
Fatigue
-A slight increase in stress above the elastic limit will result in a breakdown of the material and causes it to deform permanently
Yielding
Buckling
Creep
Strain Hardening
When yielding has ended, an increase in load can be supported by the specimen, until it reaches a maximum stress referred to as the ultimate stress
Necking
Strain Hardening
Strain Hardening
Yielding
Just after the ultimate stress, the cross sectional area will begin to decrease in a localized region of the specimen, until the specimen breaks at the fracture stress.
Necking
Strain Hardening
Yielding
