Elastic energy
|
The elastic energy is the energy stored in an elastic body and is equal to the work done to overcome the elastic force and deform the body. For a spring with spring constant k stretched by a distance x from its natural length, the elastic energy is kx 2 /2. For various small deformations, the elastic constant is λ and the strain is e , so the elastic energy is λ e 2 /2.

ひずみエネルギーともいう。弾性体内にたくわえられているエネルギーで，弾性力に打勝って弾性体を変形させるために外から加えた仕事に等しい。自然の長さから x だけ伸びたばね定数 k のばねでは，弾性エネルギーは kx2/2 ，また種々の微小変形に対して対応する弾性係数を λ ，ひずみを e とすれば λe2/2 である。
