摘要: 本文根据能量原理,从理论上给出了材料的屈服强度与伸长率、弹性模量、密度、摩尔质量、摩尔热容、摩尔熔化潜热、熔化温度、变形温度等物理性能参数和力学性能参数之间的关系式。按该式计算的材料的屈服强度与46种材料的屈服强度的实测值吻合较好。

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.
