THE EFFICACY OF THE INHERENT STRAIN METHOD IN DETERMINING RESIDUAL STRESS IN IN718 SLM SPECIMENS
South African Journal of Industrial Engineering, 2021 This paper presents a study showing the efficacy of the inherent strain method and modifications thereof to predict residual stresses within selective laser melted components. Cubic specimens with variations in hatch rotations were produced, and the residual stress state was simulated and measured by employing the neutron diffraction technique ...

On the incorporation of a micromechanical material model into the inherent strain method—Application to the modeling of selective laser melting [PDF]
GAMM-Mitteilungen, 2021 Abstract When developing reliable and useful models for selective laser melting processes of large parts, various simplifications are necessary to achieve computationally efficient simulations. Due to the complex processes taking place during the manufacturing of such parts, especially the material and heat source models influence the

A Curved Plate-Flattening Method to Construct the Membrane Strain Distribution
Journal of Marine Science and Engineering, 2023 The surface-flattening process has many applications in industries such as shipbuilding. Curved surfaces in the industry are usually formed from flat surfaces, so the target surface needs to be flattened to obtain its corresponding initial shape.
