在颗粒间距受限的情况下，通过最小化表面能和晶界能之和来确定烧结过程中形成的全同颗粒的平衡构型。计算了平衡构型的能量随粒子间距的变化。在粘结和分离两个粒子时，能量-位移曲线呈现滞后曲线。烧结力是根据能量-位移曲线的斜率计算出来的，这是停止烧结收缩所必需的力。
The equilibrium configuration of identical particles evolved during sintering was determined by minimizing the sum of surface energy and grain boundary energy for the case where the interparticle distance was constrained. The energy was calculated for the equilibrium configuration as functions of the distance between particles. The energy–displacement curve exhibited hysteresis loop at bonding and separation of two particles. The sintering force, a force necessary to just stop the sintering contraction, was calculated from the slope of energy–displacement curve.
