Precise prediction of service life for our engineering structures becomes more and more critical as we continuously search for efficient use of the material, space and mass. Engineering structures are known to be susceptible to material fatigue, which is the leading cause of mechanical in-service failures and therefore, a first-order design goal to avoid. Generally, fatigue strength is calculated with the post-processing of the local stresses and strains from an FEA simulation using various guidelines, standards, software and material databases.
This webinar will look at the effect of factors outside of the engineering office. The focus will be on the influence of surface conditions, which are unique for each casted component and additive manufactured part. These specific surface conditions have a significant impact on the real fatigue strength.
In this exclusive member webinar, Márton Gróza from NAFEMS Eastern Europe will present the results and experience of a joint industrial-academic research program conducted on nodular cast iron components. The field of defect induced fatigue will also be introduced, including the Kitagawa diagram, fracture mechanics and notch fatigue concepts.
This webinar is available to all NAFEMS members exclusively as part of their membership.
Márton Gróza is an associate of the NAFEMS Eastern European office and a PhD researcher close to his final defence with the research topic “Effect of surface defects on the fatigue life of nodular cast iron components”, which he conducted at Budapest University of Technology and Economics in cooperation with the industrial partner Knorr-Bremse Rail Systems Budapest and the French National Institute for Aerospace and Space. He is the manager of the Karman Mechanics engineering consultancy engaged in numerical simulations for the railway and defence industry.
