The applicability of the damage model under various one-dimensional loading paths and under spatial loadings is verified.
Moreover, non-proportional loading paths were studied.
Also loading paths for different branch diameters have been determined.
Different loading paths with different phase shifts were applied.
The proportionality of studied loading paths is also discussed.
Four biaxial loading paths were applied in the tests to observe the effects of multiaxial loading paths on the additional hardening, fatigue crack initiation and crack propagation orientation.
Effects of loading paths on the hydro-formability of trapezoid-sectional parts are studied and the design principle of loading paths for trapezoid-sectional parts is put forward.
Now the application of T-criterion is examined for combined loading paths of two ductile materials.
The aim is to test T-criterion's forecast for these loading paths.
All the necessary information concerning material properties, loading paths, and failure conditions is given.
The prediction of forming limit under such combined loading paths with large pre-strains is discussed.
