TL;DR: In this article, total strain controlled low cycle fatigue tests on 316L(N) stainless steel have been conducted in air at various strain rates in the temperature range of 773-873 K to identify the operative time-dependent mechanisms and to understand their influence on the cyclic deformation and fracture behaviour of the alloy.

TL;DR: The strength of the adhesive bond between o direct-filling and the cavity walls of a tooth must exceed 49 kg./cm.
Abstract: The strength of the adhesive bond between o direct-filling and the cavity walls of a tooth must exceed 49 kg./cm. 2 (700 psi), which is a conservative estimate of the tensile stress that develops during the hardening of such material. The corresponding stress for a silicate cement would be about 35 kg./cm. 2 (500 psi).

TL;DR: In this article, the springback of a simple U-bend has been calculated for one of the materials, and from the results of these simulations some conclusions regarding the choice of hardening law are drawn.

TL;DR: In this paper, a constitutive, non-isothermal unified hardening (UH) model is presented to interpret the thermo-elasto-plastic behaviors of normally consolidated and overconsolidated clays.
Abstract: A constitutive, non-isothermal unified hardening (UH) model is presented to interpret the thermo-elasto-plastic behaviours of normally consolidated and overconsolidated clays. Two yield surfaces are adopted in the proposed model: the current yield surface and the reference yield surface. A UH parameter (H) is developed to describe the evolution of the current yield surface, and the plastic volumetric strain is employed to quantify the hardening of the reference yield surface. The similarity ratio (RT) between the current yield surface and the reference yield surface, which is a function of the temperature and the plastic volumetric strain, is developed to govern the volume change behaviour and the shear strength of soils with different stress histories and at varying temperatures. The performance of the proposed model is then discussed in five typical scenarios: isotropic heating and cooling, drained/undrained triaxial compression with constant temperatures, and heating under constant non-isotropic states...

TL;DR: In this article, the solidification pathway, C-solubility and phase evolution of C-containing TiAl alloys are investigated, and the creep behavior of a refined Ti-43.5Al-4Nb-1Mo-0.5
