mixer linning plate blade
The strength and deformation properties of steel bars are mainly showed by the stress got by the uni axial tension, which is also called strain curve . The test show that the strain curve of the steel tensile stress can be divided in to two kinds: one is which has obvious flow amplitude, (picture 2-17)and another not. (picture 2-18)
