Originální abstrakt

Ductile fracture calibration needs to be done on the basis of reliable experimental testing. Reliable from the proportional loading path point of view, and the knowledge of crack initiation location too. Tubular specimen was designed and biaxially tested to be used for calibration of phenomenological criterion as well as for the comparison to other tubular biaxially tested specimens from recent literature. Calibrated phenomenological criterion was implemented by developed algorithm to Abaqus using the user subroutine in order to predict the cracking onset. The proportionality of loading path was tracked together with the evolution of state variables through the wall thickness to conclude the applicability of each specimen for a specific loading.
