摘要
运用有限元的思想,将悬臂梁化成若干三角形单元,考虑其单元的位移模式以及形态函数后,通过能量法,得到单元的刚度矩阵,而后对其进行整体分析,包括整体刚度矩阵的建立以及边界条件的引入等等。详细讨论了悬臂梁的位移以及应力和应变的变化情况,可以看出有限元针对此问题的收敛性很好。
In this paper, a cantilever beam is investigated using finite element method. Considering the displacement field in a finite element discretisation and shape function, we can get the stiffness matrix. The displacements of the cantilever beam are studied, as well as the stresses and strains, in detail. The study concludes that finite element method can be applied to cantilever beam.
