本文采用调和势和双调和势法,导出了圆盘形夹杂外部弹性场的解析表达式。得到了以本征应变表示的应力强度因子公式,并对所得结果的特征及应用作了讨论。
The expression of the elastic field round the outside of the disk inclusion has been deduced analytically by the method of the harmonic and biharmonic potentials. The formulation of the stress intensity factors of the disk inclusions in terms of its eign-strains is resulted. The aspects of the results obtsined as well as its availability have also been discussed.
