Assessment of Ductile Fracture Criteria Under Compressive Pre-strain With Digital Image Correlation
2014
Procedia Materials Science
An object of this study is to assess ductile fracture criteria for compressively pre-strained material with digital image correlation (DIC) technique and to validate the criteria by performing finite element analyses (FEA). Uniaxial tension tests, uniaxial compression tests and tensile tests after pre-compression followed by reversed-tension were conducted with round bar and cylindrical specimens of A2024-T351 aluminum alloy. The radii of the minimum sections of the specimens at ductile crack
