Abstract:
According to the energy principle, theoretical relationship formula
of yield strength in respect of physical and mechanical properties, such
as elongation, elastic modulus, density, Molar quality, Molar heat
capacity, Molar melting heat, melting point and deformation temperature
etc. has been derived. Yield strength calculated from the formula shows
good accordance with experimental data of 40 kinds of materials.
