PSAD 1

Front

The energy stored in a material due to its deformation.

Back

strain energy

Front

The maximum amount of strain-energy the material can absorb just before it fractures.

Back

modulus of toughness

Front

The largest amount of internal strain energy per unit volume the material can absorb without causing permanent damage.

Back

modulus of resilience

Front

The property of a material that allows it to return to its original state when the load is removed.

Back

elasticity

Front

The ability of a material to deform in the plastic range without breaking.

Back

ductility

Front

The ability to resist deformation within the linear range, equal to the amount of force required to produce unit deformation.

Back

stiffness

Front

A material’s resistance to fracture.

Back

toughness

Front

A material’s resistance to indentation.

Back

hardness

Front

Any material that can be subjected to large strains before it fractures.

Back

ductile material

Front

Materials that exhibit little or no yielding before failure.

Back

brittle materials
