The yield strength or yield stress is a material property and is the stress corresponding to the yield point at which the material begins to deform plastically. The yield strength is often used to determine the maximum allowable load in a mechanical component, since it represents the upper limit to forces that can be applied without producing ...
The cold working of the metal increases the hardness, yield strength, ... K is the strength index or strength coefficient, ε p is the plastic strain and n is the ...
The yield strength is the point at which elastic deformation gives way to plastic deformation. Deformation in the plastic range is non-linear, and is described by the stress-strain curve. This response produces the observed properties of scratch and indentation hardness, as described and measured in materials science.
The critical resolved shear stress for single crystals is defined by Schmid’s law τ CRSS =σ y /m, where σ y is the yield strength of the single crystal and m is the Schmid factor. The Schmid factor comprises two variables λ and φ, defining the angle between the slip plane direction and the tensile force applied, and the angle between the ...
POM is characterized by its high strength, hardness and rigidity to −40 °C. ... melt-processable plastic. ... Elongation at yield 2.5 % Tensile breaking stress 67
High-strength steels have comparable yield strengths, and low-carbon steels have yield strengths much lower (around 0.5 GPa (73,000 psi)). Since steel has a specific gravity of roughly 7.8, these materials have a strength-to-weight ratios eight times that of high-strength steels.
The Vickers hardness test was developed in ... is to observe a material's ability to resist plastic ... where c is a constant determined by yield strength, ...
In one study, strain hardening exponent values extracted from tensile data from 58 steel pipes from natural gas pipelines were found to range from 0.08 to 0.25, [1] with the lower end of the range dominated by high-strength low alloy steels and the upper end of the range mostly normalized steels.
