摘要: A review covering the present state of yield strength of metals and alloys is presented. Emphasis is placed on slip and dislocation, multiplication of dislocations, plastic flow rate equation, Peierls stress, temperature dependence of the yield stress and effect of solute atoms....
When yield strength is reported, the amount of offset used in the determination should be stated. For example, "Yield Strength (at <0.2% offset) = 51,200 psi."Young's Modulus of Common Engineering Materials Some examples of yield strength for metals are as follows....
Towards Balanced Strength and Plasticity in Graphene-Nickel Composites: The Role of Graphene, Bimodal Metal Powder and Processing Conditions Due to their higher strength and lighter weight compared to conventional metals, graphene-nickel (Gr-Ni) composites have recently gained growing interest f...

This is the most widely used strength measure of metals, and is found from the stress-strain curve as shown in the figure to the right. A plastic strain of 0.2% is usually used to define the offset yield stress, although other values may be used depending on the material and the applica...
the yield strength is chosen to be that strength when a definite amount of plastic strain has occurred. For the generastructural design, the yield strength is chosen when 0,2 percent plastic strain has taken place. The 0.2% yield strength or the 0.2% offset yield strength is calculated at ...

In general, the shear strength of metals and alloys in cutting has been found to vary only slightly over a wide range of cutting speeds and feeds [8]. The problem is to correlate the shear stress magnitude in cutting with relevant values of shear yield strength determined in tensile, compres...
We present results of testing soft and high-strength steels for impact compression and show that the dependences of the compression resistance of tested metals on the level of strains are qualitatively similar. It is also shown that, as the strain rate increases, the compression resistance of the...
