论文摘要
比软柔软的颗粒物柔软的颗粒物由能够显着改变其形状（通常大于变形的10％）而不会撕裂或破裂的晶粒组成。由于难以通过实验和数字测试这些材料，尽管在大自然和工业中通常发现了这种离散系统家族在颗粒物物理领域仍在很大程度上被忽略。从数值，实验性或分析的角度来看，对高度变形的颗粒物的研究涉及几个挑战，例如：（$ i $）需要包括大量谷物流变学，（$ ii $）需要考虑\ dc {gialt y材料}的不适范围，并且（$ iii $ $ iii $）的分析对大体内的效果进行了分析。在本文中，我们提出了对这些柔软的颗粒系统的彻底定义，并总结了他们的研究中即将面临的挑战。
Softer than soft, squishy granular matter is composed of grains capable of significantly changing their shape (typically larger than 10% of deformation) without tearing or breaking. Because of the difficulty to test these materials experimentally and numerically, such a family of discrete systems remains largely ignored in the granular matter physics field despite being commonly found in nature and industry. Either from a numerical, experimental, or analytical point of view, the study of highly deformable granular matter involves several challenges covering, for instance: ($i$) the need to include a large diversity of grain rheology, ($ii$) the need to consider \dc{large material} deformations, and ($iii$) the analysis upon the effects the large body distortion has on the global scale. In this article, we propose a thorough definition of these squishy granular systems, and we summarize the upcoming challenges in their study.
