In this work, a methodology is presented to predict yield stresses from the force vs. deflection curves. The present method relies on determining different force levels from the initial part of the force-deflection curve to reflect both the slope and the curvature instead of using a single force level only. The predicted yield stresses for different types of materials, that is, low- and high-strength alloys, are found to be in good agreement with the actual proof stresses with a maximum error of 16%.eninfo:eu-repo/semantics/closedAccessMechanical-propertiesCreep-propertiesP91 weldmentFractureSpecimenSteelsSmall punch testDeflectionYield stressFinite element methodScience & technologyPhysical sciencesTechnologyChemistry, physicalMaterials science, multidisciplinaryMetallurgy & metallurgical engineeringPhysics, appliedPhysics, condensed matterChemistryMaterials scienceMetallurgy & metallurgical engineeringPhysicsArticle000555016400001131210.3390/ma13122840
