【摘要】 研究了直流电场中微小玻璃球（直径约为２２０μｍ） 以矩形或立方结构在硅油中形成的“链组”的剪切力学行为，观察了链及链组的形成、剪切、屈服和断裂过程．发现链组的剪切强度随组成链组的链数和电场强度的增加而增加，链组的剪切模量与组成链组的链数几乎无关， 仅随电场强度的增加而增加．更多还原

【Abstract】 The mechanical behavior of sheared cluster formed in silicone oil with a rectangular or cubic lattice is studied under DC electrical field. The cluster consists of small humidity glass spheres (diameter is about 220μm). The processes of formation, shearing, yield and fracture of the cluster were observed. It is found that the shearing strength of a cluster increases with the chain number in the cluster and the electrical field strength. The shear modulus is almost independent of the chain number in a cluster, but increases with applied electric field.更多还原
