上期我们谈到了梁的内力图绘制,本文分析梁变形的两种基本计算方法,以及应力图与微体的对应关系,供同学们参考。 一、梁的变形 梁的变形与梁的内力、应力在材料力学中占有同等重要的地位,梁的变形有两种计算方法: (一)积分法 ①分段列出微分方程,各梁段的自变量x应取同一原点(一般取左端)。 ②后一梁段的弯矩方程保留前一梁段弯 In the last issue, we talked about the internal force mapping of beams. In this paper, we analyze two basic calculation methods of beam deformation, and the correspondence between stress maps and micro-bodies for the reference of the students. First, the beam deformation Deformation and the beam beam internal forces, stress in the material mechanics occupy an equally important position, beam deformation in two ways: (A) integral method ① differential equations listed in section, the beam section Argument x should take the same origin (generally take the left). ② Bending moment equation of the first beam section Bending the previous beam section
