层状结构顶面当量模量的近似计算

Approximate Calculation of Equivalent Modulus of End Face of Laye red Structures

给出了单圆轮载和双圆轮载作用下不同层间接触条件 (光滑、连续 )的双层结构顶面当量模量回归显式 ,多层结构的近似换算式。这些公式具有物理意义明确 ,外延性好 。

The regression expressions for equivalent modulus of end face of two layered and multi layered structures with smooth or continuous interlayer contact condition are derived. These expressions have the advantages of clear physical meaning, good extrapolation and high precision.
