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.

New Concept of Equivalent Inherent Strain for Measuring Axisymmetric Residual Stresses

Journal of Manufacturing Science and Engineering, 1997
A new concept, the equivalent inherent strain gθeq, is proposed for measuring axisymmetric residual stresses, based on the inherent strain theory. gθeq is a parameter obtained by incorporating the radial inherent strain component into the tangential inherent strain component in computing the axially uniform axisymmetric residual stresses.
