Yield was then defined as the bisection of the two linear portions at their intersection, tangentially projected onto the logarithmic bridge, which it intersects at a right angle. Yield strengths were also calculated through retention of the bilinear approximation and the 0.2% offset technique. A ...
This may be attributed to strain hardening of the aluminum during stretching and the residual compressive stress in the metal layers after stretching, which increases the applied stress at which yielding of these layers occurs. The use of high yield strength 7075-T6 in ARALL-1 and -3 laminates...
Quasi-Static Strength, Deformation, and Fracture Behavior of Aluminum–Lithium Alloys Anisotropy in Yield Strength Yield strength anisotropy has attracted much interest. Two major influences are the crystallographic texture and the final heat-treatment condition. The use of high levels of zirconium (Zr)...
and the means were compared using the LSD test. It was observed that the microbial fertiliser did not adversely effect on the growth characteristics of lettuce and even had an ameliorative effect. The highest root dry weights were obtained in the T7, T3, ...
Gotoh's 1977 Yield Stress Function with Kinematic Hardening for Modeling Strength Differential Yielding of Orthotropic Sheet Metals Jie Sheng, Seung-Yong Yang, and Wei Tong Abstract When a sheet metal is subjected to both tensile and compressive stresses in a forming process, there is a need to ...
The strength differential effect has been also observed by Gil et al. [31], [32] in the aged Inconel 718, a nickel-base superalloy used extensively for aeropropulsion structures. The elastic properties of the material are E = 165 GPa and ν = 0.297, and the stress–strain responses in ...
The experimental results presented in their publication showed a significant increase in the stress rate sensitivity beyond 103 s−1 for a high-strength steel. Furthermore, a recent publication explicitly considered the abrupt yield stress increase in LSP-treated OFHC (oxygen-free high thermal ...
Two factors of indentation size effects in PMMA, namely yield criterion and shear transformation-mediated plasticity, were analysed in detail. The yield criterion that considers strength differential (SD) effects and pressure sensitivity was constructed by performing the combined shear-compression ...
