Finite strain fitting
WebDec 1, 2010 · The best-fitting answer, which defines an oblate ellipsoid, was: S 1 = 3.15, S 2 = 1.11, and S 3 = 0.286. Thus, the Twin Sisters has an oblate-shaped finite strain ellipsoid, the long axis of which plunges 40°SE. This result is consistent with thinning of the planar dikes in both the horizontal and vertical directions. WebNov 1, 2024 · 1. Introduction. Shrink-fit connections are widely used in machine design. It is the very old method of connecting an assembly parts [1].Current research consider using shrink-fit connections in the reactor vessels of the nuclear power plants [2], in gear mechanism's parts [3, 4] and in crank shafts of ships [5, 6, 7].In the papers [3, 8, 9], the …
