中文拼音 [zhùmiànjízuòbiāoxì]
柱面極坐標系
英文
cylindrial polar coordinate system-
Eigenequation about singularity, singular stress fields and electrical displacement fields near the interface edge are obtained under axisymmetric distortion. finally, a special finite element formulation which is based on the principle of minimum potential energy has been developed for determining the orders of the singularity of the singular stress fields around the singular point ( interface edge, interface corner and the interface crack ) in the bonded dissimilar anisotropic / anisotropic, piezoelectric / piezoelectric as well as piezoelectric / anisotropic materials. the numerical results show that this method is very convenient and efficient
最後,從最小勢能原理出發,在僅僅考慮奇異性支配區域這一前提下,對于彈性接合材料的平面變形問題和擬平面應變問題,以奇異點為原點分別建立極坐標系和圓柱坐標系,通過分部積分消除廠項,從而使奇異性問題的求解由原來的二維降為一維;對於三維變形問題,以奇異點為原點建立球坐標系,通過分部積分消除項,從而使奇異性問題的求解由原來的三維降為二維。
