About a Digital Twin for the Fatigue Approach of Additively Manufactured Components
2019
A digital twin is an image of the reality. In case of a digital twin for additively manufactured components by the use of selective laser melting and Inconel®718 issues as microstructure, anisotropy and load history are discussed. In order to take the main influences on the cyclic material behavior into account, local stresses and strains of a structure element are introduced. Furthermore, this new interpretation of the local load properties enables a two-stage combined macroscopic and microscopic material image as the basis for a digital twin for the fatigue assessment of additively manufactured components.
