The paper provides some results of the investigation of the influence of stress state type on accumulation of dispersed damages in structural carbon steel sheet under repeated static biaxial tensile loading. It is shown that the lowest damage accumulation ability of the metal is observed under biaxial tension with a biaxiality index ranging between 0.25 and 0.3. [ABSTRACT FROM AUTHOR]
The paper addresses the well-known (from available publications) phenomenological strength criteria for anisotropic materials, which are most widely used in application software. [ABSTRACT FROM AUTHOR]
