Abstract

Impact-oscillatory loading of variable intensity was applied to the VT23M high-strength sheet two-phase titanium alloy in liquid nitrogen. This was carried out to investigate the effect of this loading type on changes in the mechanical properties and structural condition of the alloy upon subsequent static tensioning at normal temperature. Dynamic non-equilibrium process (DNP) realized at a temperature of liquid nitrogen proved to be unable to impair the strength properties of the VT23M titanium alloy compared to room temperature; however, they caused a significant decrease in ductility (down to 16%). The impaired plastic properties of the alloy were shown to entail additional defects in the structural components of the alloy. The authors have found patterns of damage accumulation in the structural components of the alloy depending on the DNP parameters. They are in good agreement with the findings of the fractographic research. [ABSTRACT FROM AUTHOR]

Abstract

The results of a study of the influence of low-cycle loading of the aluminum alloy D16ChATV, after a previous combined loading, on its plasticity. The previous combined load (PCL) was applied with the help of a short-term external force impulse superimposed on the main monotonic load by stretching. The residual fatigue strength of the material after the PCL is estimated using the deformation and energy criteria. The peculiarities of the changes in the micro-pattern of the surface of fracture of the material are analyzed to identify the main mechanisms of micro-deformation and fracture of materials.

Abstract

New experimental results on the effect of additional force impulse loading on the variation of the initial structure of the aircraft material (alloys D16, 2024-T3, VT22) at various stages of deformation are presented and a significant enhancement of its initial plasticity is achieved. Complex investigations into the material properties after a dynamic non-equilibrium process made it possible to describe the main regularities in the nature of deformation and fracture of materials, which allowed proposing general recommendations on using the revealed physical and mechanical regularities in the evaluation of strength of aircraft structures.

38. Strain field evolution on the surface of aluminum sheet alloys exposed to specific impact with oscillation loading.

Author

Abstract

Strain field evolution on the surface of aluminum sheet D16 and 2024-T3 alloys has been analyzed during static deformation and during specific high-speed impact and oscillation loading—dynamical non-equilibrium process. Experiments have been conducted using an original mechanical testing technique and a specially developed software solution for non-contact study of strain field using digital image correlation fitted with a high-speed camera. It has been established that deformation process kinetics for tested aluminum alloys after a dynamical non-equilibrium process during further static deformation changes as compared with a process of static deformation mainly manifests itself in the increase in general alloy ductility and delay in “neck formation.” It has been shown that strain field is an important indicator for deformation band structure formation in the tested materials.
