Compressive stress and shear stress on the deformation mechanism of Mg-13Gd-4Y–2Zn-0.5Zr alloy at different deformation temperatures

Journal of Materials Research and Technology, 2022
At present, alloys are affected by various stress states during their deformation process. Various stresses can facilitate alloy deformation at the same time, and the influence of these stresses on material deformation is difficult to clarify.

Development of the Metal Rheology Model of High-temperature Deformation for Modeling by Finite Element Method [PDF]

, 2019
It is shown that when modeling the processes of forging and stamping, it is necessary to take into account not only the hardening of the material, but also softening, which occurs during hot processing.

A new sinusoidal shear deformation theory for bending, buckling, and vibration of functionally graded plates [PDF]

, 2012
A new sinusoidal shear deformation theory is developed for bending, buckling, and vibration of functionally graded plates. The theory accounts for sinusoidal distribution of transverse shear stress, and satisfies the free transverse shear stress ...

Loss of strength in Ni3Al at elevated temperatures [PDF]

, 2006
Stress decrease above the stress peak temperature (750 K) is studied in h123i single crystals of Ni3(Al, 3 at.% Hf ). Two thermally activated deformation mechanisms are evidenced on the basis of stress relaxation and strain rate change experiments.
