Abstract A characteristic tensor is defined using stress tensor averaged in a small
circular domain at the crack tip and multiplied by the root of domain radius. It possesses
the original stress tensor characteristics and has a simple relationship with conventional
fracture-mechanics parameters. Therefore, it can be used to estimate stress intensity
factors (SIFs) for cracks of arbitrary shape subjected to multiaxial stress loads. A
characteristic tensor can also be used to estimate SIFs for kinked cracks. This study
examines the relation between a characteristic tensor and SIFs to demonstrate the
correlation between the characteristic tensor and fracture-mechanics parameters.
