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 U is the modulus of resilience, σ is the yield strength, and E is the Young's modulus.
Famous quotes containing the word resilience:
“Toddlers who don’t learn gradually about disappointment lose their resilience through lack of practice in give-and-take with other people’s needs. They can become self-centered, demanding, and difficult to like or to be with.”
—Alicia F. Lieberman (20th century)
