Calculation of multiple (multiaxial) notches according to DIN 743 by integration of FEM results

Full title:	Calculation of multiple (multiaxial) notches according to DIN 743 by integration of FEM results
Duration:	10/2013 - 06/2015
Contributors:	Dipl.-Ing. Jörg Wendler Dipl.-Ing. Felix Kresinsky (TU Chemnitz, IKAT)
Financing:	Forschungsvereinigung Antriebstechnik (FVA)
Project partners:	Institut für Konstrukions-und Antriebstechnik (IKAT) Technical University Chemnitz
Objective:	Linking of FE analysis and proven load capacity analyses according to DIN 743 Preparation of guidelines for modelling and evaluation of FE models Enabling strength verification for shafts and axles of notch cases not mentioned in DIN 743
Approach:	Derivation of a method for the integration of local multiaxial stress states into the nominal stress concept based on stress mechanics Numerical analyses (FEM) of typical applications of shafts (multiple notches) Comparison with experimental results of previous and current research projects
Results:	A provided guideline for modelling and evaluation enables the user to calculate individually designed multiple notches and to provide a standardised strength verification.
