| 1 | 三维边界元法中高阶单元上的几乎奇异积分显示文摘三维边界元分析中,高阶几何单元上的几乎奇异积分计算是一个重要而且困难的问题,该文对此进行了研究.使用8节点四边形和6节点三角形曲面单元来描述几何边界;构造了新的距离函数;拓展原有的指数函数非线性变换到三维边界元法中,利用拓展的变换来消除被积函数的几乎奇异性.数值算例表明,该算法稳定,效率高,即使计算点到实际边界的距离很小,依然可获得令人满意的数值解. | 张耀明 李小超 Vladimir Sladek Jan Sladek | 2013 | 力学学报2013，45，6： | 3 |

| 4 | Perturbation finite element solution for chemo-elastic boundary value problems under chemical equilibrium显示文摘Modeling the elastic behavior of solids in energy conversion and storage devices such as fuel cells and lithium-ion batteries is usually difficult because of the nonlinear characteristics and the coupled chemo-mechanical behavior of these solids.In this work,a perturbation finite element(FE)formulation is developed to analyze chemo-elastic boundary value problems(BVPs)under chemical equilibrium.The perturbation method is applied to the FE equations because of the nonlinearity in the chemical potential expression as a function of solute concentration.The compositional expansion coefficient is used as the perturbation parameter.After the perturbation expansion,a system of partial differential equations for the displacement and dimensionless solute concentration functions is obtained and solved in consecutive steps.The presence of a numerical solution enables modeling 3D chemo-elastic solids,such as battery electrodes or ionic gels,of any geometric shape with defects of different shapes.The proposed method is tested in several numerical examples such as plates with circular or elliptical holes,and cracks.The numerical examples showed how the shape of the defect can change the distribution of solute concentration around the defect.Cracks in chemo-elastic solids create sharp peaks in solute concentration around crack tips,and the intensity of these peaks increases as the far field solute concentration decreases. | Peter L.Bishay Jan Sladek Nicholas Fabry Vladimir Sladek Chuanzeng Zhang | 2019 | Acta Mechanica Sinica2019，35，5： | 1 |
