WebFeb 12, 2024 · Rock fracture is a pertinent problem of the rock engineering study. The basic patterns of the rock failure are a deterministic factor for the design of the rock pillars in the mines. The extent of variability of the rock properties is very high even within the same rock types. Thus, laboratory tests are very important in rock mechanics whereby the failure … WebOct 15, 2015 · Considering the effects of profile shift and tooth crack, Time-varying mesh stiffness (TVMS) is determined based on an analytical model and the result accuracy is also verified by Finite element (FE) model. Then, by introducing TVMS into the FE model of a gear rotor system, the combined effects of profile shifted gear pair under positive, …
