基于圣文南原理和叠加原理,计算了单边裂纹梁在横向力弯曲下的应力强度因子。导出了计算K_Ⅰ和K_Ⅱ的简单公式,并讨论了这些公式的适用条件。
The stress intensity factors of a single-edge cracked bar loaded by in-planetransverse forces are calculated with the application of the principle of superposition, and St. Venant's Principle. Simple formulae for K_Ⅰ and K_Ⅱ are derivedand the appropriate conditions under which these formulae are applicable havebeen discussed.
