本文提出了一种由单晶体的弹性常数计算衍射弹性常数的逆Kroner模型。它与经典的Kroner模型有关，两者都被确定为衍射弹性常数的界限。通过晶粒形状作为控制参数，经典Kroner模型由矩阵的体弹性常数给出的hkl无关的机械极限约束，而逆Kroner模型接近Reuss极限。
A model, dubbed the inverse Kroner model, is proposed to calculate the diffraction elastic constants from the elastic constants of a single crystal. It is related to the classic Kroner model, and both are identified as bounds on the diffraction elastic constants. Through the grain shape as controlling parameter, the classic Kroner model is bound by the hkl-independent mechanical limit given by the bulk elastic constants of the matrix, while the inverse Kroner model approaches the Reuss limit.
