Abstract
Additively manufactured materials usually exhibit mesoscale heterogeneities. Mesoscale fluctuations of strain fields in notched samples made of 17-4PH Stainless steel and loaded in tension are investigated. Regularized digital image correlation enables for the analysis of strain fluctuations at different length scales. Five tests on specimen fabricated with different printing parameters are studied. It is shown that the strain fluctuations have no characteristic length scale and are essentially independent of the probed processing parameters.
期刊介绍：
The Journal of Strain Analysis for Engineering Design provides a forum for work relating to the measurement and analysis of strain that is appropriate to engineering design and practice.
"Since launching in 1965, The Journal of Strain Analysis has been a collegiate effort, dedicated to providing exemplary service to our authors. We welcome contributions related to analytical, experimental, and numerical techniques for the analysis and/or measurement of stress and/or strain, or studies of relevant material properties and failure modes. Our international Editorial Board contains experts in all of these fields and is keen to encourage papers on novel techniques and innovative applications." Professor Eann Patterson - University of Liverpool, UK
