摘要：

During pressure consolidation of powder compacts, particle rearrangement leading to nonrecoverable strain can be observed. In this study rearrangement is identified as a buckling mechanism that occurs in particle arches. The mechanism is initiated when the applied pressure generates a critical contact force at an arch within the powder compact. The consequence of the buckling is localized consolidation. The contact forces required to initiate this mechanism on a particle scale are evaluated. It is shown that this snap-through-buckle mechanism could play a significant role in powder consolidation.
