Simultaneous considerations of length and boundary conditions on theoretical stress concentration factors

This work is concerned with the consequences of switching the uniformly loaded end, and accordingly the supported end, that is, exchanging boundary conditions in shouldered shafts with fillet radius, subjected to uniform tension, on the resulting stress concentration factor magnitudes when the length of the member is taken into account. Notably different values of the stated factors result under the conditions of the study reported herein. An issue of importance is the reliability of design and analyses involving fatigue of mechanical and structural members. Transition length values from long to short length regimes are reported as well. (C) 2003 Elsevier Science Ltd. All rights reserved.
