چکیده انگلیسی
A new approach has been suggested for the construction of long-term fracture criteria under creep conditions and multi-axial loading. The method developed overcomes former problems with a view to identifying stresses responsible for failure and material constants, and is based on the equivalent long-term strength diagrams. The criteria are chosen in the form of a mixed invariant relating two stress components, which give rise to brittle and viscous fracture. The values of stress characteristics combined in a mixed invariant take signs of principal stresses into account. The fracture criteria derived have been approved on unified long-term strength diagrams of thin-walled tubular specimens under internal pressure, internal pressure with tension, pure torsion and tension with torsion.
