Gammarus baysali sp. nov., a new freshwater amphipod species from Turkey (Amphipoda: Gammaridae)

This paper presents the boundary element analysis of interference fit problems using axisymmetric boundary elements. A subregional technique is used to calculate the interference pressure and to find the von Mises stresses on the hub bore, without using iteration and incremental methods. The shaft and hub are modelled with equal lengths, unequal lengths, a shoulder on the shaft, and a grooved hub. Axisymmetric models of the shaft and hub are used to determine variable interference pressure along the interface line in the axial direction. The hub material is considered as steel and grey cast iron, and the shaft material is taken to be steel. All models used in the analysis are also solved using the finite element method with the ANSYS program. The results are compared with each other.
