【摘要】 本文从弹性理论基本方程出发,根据截面变形几何相似假定,应用两个变形分布函数,建立一种广义厚板振动方程。这种方程将包含和统一日前各种厚板理论,其相应的应力表达式将缩小与三维方程精确解的差距。更多还原

【Abstract】 In this paper, starting from the fundamental equations of theory of elasticity, according to the assumption about geometrical similarity of section deformations, using two deformation distributive functions, a generalized vibration equation of thick plates is deduced. This equation includes and unites present various theories of thick plates. Its corresponding stress expression approaches to exact solution of three dimensional equations.更多还原
