stress around opening
Examples
- According to the fundamental theories of elastic mechanics and superposition principle , this paper presented a complex functional solution which is numerically effective for solving the stress concentration problem in an infinite two - dimensional elatromer with arbitrary shaped holes by introducing conformal mapping technique
本文的第一部分根据弹性力学中求解平面孔口问题的基本理论，利用叠加原理，引入保角变换技术给出了适合数值计算的无限大平板一般形状孔口应力集中问题的复变函数解。 - Then the writer finished elastic and nonlinear analysis to slabs with different openings and different boundary by finite calculation . and the writer made comparison to all dates and got the change rule of the stress , displacement , limit load and crack of slabs with openings where changing the each parameter
接着，笔者采用有限元程序对不同开孔大小、不同开孔位置、不同的边界条件进行了弹性和塑性分析，并结合实验数据和前人数据，分析出各种不同条件下开孔板在孔口应力、挠度、极限承载力、裂缝形式等的变化规律。 - 4 ) three - dimensional nonlinear analysis of the bottom outlet of the xiao wan arch dam is presented using sub - model techniques . the structural characteristics and failure mechanism of the bottom outlet , under loading of concrete deadweight , hydraulic pressure , internal water pressure and temperature are studied . it is shown that the meshing of the structure becomes easy and the computing time is reduced by using sub - modeling method
