• An automatic fatigue crack growth algorithm was used to evaluate the influence of in-phase and out-of-phase loadings in FCG. In-phase lead deflection under a 0.5 biaxial load ratio due mixed mode loading conditions. Fatigue life is proportional initial notch angle but inversely phase shift. Crack propagation direction influenced by combination static cyclic on different axes. Different freque...

Underground excavation is a necessary process for constructing mines, tunnels and depots in granite rock mass. In this study, the numerical specimens were established by discrete element method confirmed laboratory experiments order to investigate peak stress, cracking development failure properties of pre-holed under coupled biaxial loading unloading conditions. The results show that, containi...

The experimental and theoretical analysis of thermodynamical peculiarities heat flux at the fatigue crack tip during its propagation was made in presented work. goal is to elucidate relation between flow kinetic for different loading conditions. plane specimens with notch from stainless steel (AISI 304) were studied. There two types uniaxial one type biaxial loading. A dissipation measured by s...

All impact analyses performed so far for the composite plates, have treated central impacts. Furthermore, investigations on influences of the in-plane biaxial compression, tension, or tension-compression preloads on various responses of the low-velocity impact, especially the indentation, have not been performed so far. In the present research, a finite element formulation is presented for resp...
