Application of Fictitious Radius to Fatigue Life Calculations of Bending Notched Specimens

Abstract:

The paper contains an application of Neuber's fictitious radius methods to fatigue life calculations for elements with geometrical notches. FEM analysis for notched specimen with fictitious radius were performed, then results of simulations and experimental tests for smooth and notched specimens made of S355J2G1W structural steel were compared by each other. Based on simulation results, function dependence of micro structural length was determined, both for linear-elastic and elasto-plastic calculation.
