摘要
基于虚裂纹模型的概念 ,导出了无限大板中心直裂纹在远场均匀拉应力作用下双参数模型的应力函数和位移函数 ,其解由线弹性断裂力学解、Dudale的解答和加权积分法导出的虚裂纹模型解所构成 。
Based on fictitious crack model (FCM) and Two-parameter model (TPFM),an infinite plate with a central straight crack under uniform tension is analyzed in this paper. The analytical solution is derived by superposition of the linear fracture mechanics solution, the Dugdale model solution and the FCM solution by using the weight integral method. The relationship between fictitious crack length and stress intensity factor or crack opening displacement is also given.
