Analysis of stress and electric field concentration in a functionally graded piezoelectric plate with a circular hole based on nonhomogeneous smoothed finite element method
摘要
Abstract
In order to improve the calculation precision of stress and electric field concentration factor for the functionally graded piezoelectric plate with a circular hole, electromechanical coupling nonhomogeneous cell-based smoothed finite element method was proposed. Real material properties of Gaussian point were used to calculate. Stress and electric field concentration factor of functionally graded piezoelectric plate with a hole was studied, in which material properties of the piezoelectric plate was changing exponentially in a certain direction. The results show that this method has high precision in calculating stress and electric field concentration factor for the functionally graded piezoelectric plate.关键词
