论文摘要
我们从数值上研究无摩擦软球的剪切干扰过渡的临界行为和边际稳定性，观察到在有限的密度范围内发生，与各向同性堵塞有关，以高于最小堵塞（J-Point）密度的密度。显示了几个数量以与各向同性干扰点相同的方式在剪切干扰点附近扩展。我们计算与较小的力分布和颗粒间隙分布相关的指数，并表明相应的指数与观察到的各向同性干扰的边缘稳定性条件以及对硬球障碍的平均场理论的预测一致。
We study numerically the critical behavior and marginal stability of the shear jamming transition for frictionless soft spheres, observed to occur over a finite range of densities, associated with isotropic jamming for densities above the minimum jamming (J-point) density. Several quantities are shown to scale near the shear jamming point in the same way as the isotropic jamming point. We compute the exponents associated with the small force distribution and the interparticle gap distribution,and show that the corresponding exponents are consistent with the marginal stability condition observed for isotropic jamming, and with predictions of the mean field theory of jamming in hard spheres.
