论文摘要
当应用外部振荡时，我们从数值上研究糊状的应力分布。糊状物记住振荡为塑性变形。由于塑性变形，振荡后残留应力保留，其中残留应力分布取决于振荡中循环的数量。随着该数量的增加，应力分布的对称性得到了增强，这与使用干燥糊剂在实验中观察到的裂纹模式一致。
We numerically investigate the stress distribution of a paste when an external oscillation is applied. The paste memorizes the oscillation as plastic deformation. Due to the plastic deformation, the residual stress remains after the oscillation, where the residual stress distribution depends on the number of cycles in the oscillation. As this number increases, the symmetry of the stress distribution is enhanced, which is consistent with the crack patterns observed in the experiments using a drying paste.
