Strain Conversion Between Inner and Outer Surfaces of Cracked Thin-Walled Tubes: Quantitative Investigation and Unified Predictive Model
Strain conversion between inner and outer surfaces is critical for the integrity assessment of cracked thin-walled tubes, yet its dependence on crack geometry remains insufficiently clarified. In this study, X46 tubular specimens with surface and through-wall cracks were tested under uniaxial tension, with full-field d...
