noun

1. The ability to recover quickly from depression or discouragement: bounce, buoyancy, elasticity, resiliency. See ability/inability.
2. The quality or state of being flexible: bounce, ductility, elasticity, flexibility, flexibleness, give, malleability, malleableness, plasticity, pliability, pliableness, pliancy, pliantness, resiliency, spring, springiness, suppleness. Obsolete flexure. See flexible/rigid.

Definition: flexibility
Antonyms: fragility, inflexibility, rigidity

n

Definition: strength of character
Antonyms: vulnerability, weakness

The ability of a body that has been subjected to an external force to recover its size and shape, following deformation.

A measure of a body's resistance to deformation. Resilience is usually defined as the work required to deform an elastic body to its elastic limit divided by the volume of the body.

1. an act of springing back. n 2. capability of a strained body to recover its size and shape after deformation. n 3. the recoverable potential energy of an elastic solid body or stricture resulting from its having been subjected to stress not exceeding the elastic limit.

For other uses, see Resilience (disambiguation).

The area under the linear portion of a stress-strain curve is the resilience of the material

Resilience is the ability of a material to absorb energy when it is deformed elastically, and release that energy upon unloading. The modulus of resilience is defined as the maximum energy that can be absorbed per unit volume without creating a permanent distortion. It can be calculated by integrating the stress-strain curve from zero to the elastic limit. In uniaxial tension,

where Ur is the modulus of resilience, σy is the yield strength, and E is the Young's modulus.^[1]
