The influence of temperature on the structural and mechanical properties (0.9 C - 13.95 Mn) steel was investigated in this work. high-manganese has underwent aging treatments at temperatures 700, 750, 800 850 °C for different times. experimental techniques used are hardness test, scanning electron microscopy, optical microscopy X-ray diffraction. behavior microstructural evolution during almost...

The role of polygalacturonase (PG) in the development, ripening, and softening of fruit from two strawberry cultivars with different flesh firmness and softening characteristics was compared. Changes in PG activity and gene expression during development, ripening and softening were measured. The PG genes from each cultivar were cloned and analyzed, and were classified with other PG genes using ...

To investigate the thermal deformation behavior of Ti–10V–2Cr–3Al titanium alloy, hot compression experiments were carried out via a strain rate 0.1–0.001 s−1 and temperature 730~880 °C. The results showed that rheological stress decreases when increases or decreases. Due to conditions, some flow curves exhibited significant discontinuous yielding softening. Flow softening in α+β phase region w...

In this investigation, the three-parameter Modified Mohr–Coulomb (MMC) fracture model and the determination of the material parameters are briefly described. The formulation of the post-initiation behavior is proposed by defining both the explicit softening law and the incremental damage evolution law. As opposed to the existing attempts to simulate slant fracture with material weakening before...

Until the 1990s, the passive and active length-tension (L-T) relationships of smooth muscle were believed to be static, with a single passive force value and a single maximum active force value for each muscle length. However, recent studies have demonstrated that the active L-T relationship in airway smooth muscle is dynamic and adapts to length changes over a period of time. Furthermore, our ...

5.1 Abstract The change in the configurational enthalpy of metallic-glass-forming liquids induced by mechanical deformation and its effect on elastic softening is assessed. The acoustically measured shear modulus is found to decrease with increasing configurational enthalpy by a dependence similar to one obtained by softening via thermal annealing. This establishes that elastic softening is gov...
