Abstract: This article presents a piezo-actuated microgripper characterized by large amplification ratio and compact structure size. The microgripper is actuated by a piezo-stack actuator that is integrated with a two-stage displacement ...

Abstract: AbstractCasing deformation in horizontal shale gas wells is a critical issue during multistage hydraulic fracturing. This study investigates the impact of fracture density and its nonuniformity on casing deformation using ...
