摘要
我们分别计算了过冷液体和泡沫模型在玻璃化转变和堵塞转变附近粒子间法向力的分布。在玻璃化或堵塞转变附近形成一个峰，其高度随温度降低、剪切应力减小和堆积密度增加而增大。在静态颗粒堆积的实验中观察到了的类似形状。我们提出该峰的出现标志着屈服应力的产生。该峰对温度、剪切应力和密度的敏感性为近期提出的广义堵塞相图提供了佐证。

4 pages, 3 postscript figures;Version 3 replaces figure 1 and removes figure 2 from version 1. Significant rewording of version 1 to emphasize the formation of peak in P(F) when these systems jam along five different routes of the recently proposed jamming phase diagram. Version 2 displayed the incorrect abstract
