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 ...

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...
. Tensile test measures the resistance of a material to a static or slowly applied force. Machined specimen is placed in the testing machine and load is applied. Strain gage or extensometer is used to measure elongation. The stress obtained at the highest applied force is theTensile Strength....
Yield strength is one of the types of tensile strength.Yield strengthis defined as the yield stress, which is actually thestresslevel at which a permanent deformation of 0.2% of the original dimension of the material happens, and is defined as the stress level at which amaterialcan withstand ...
