摘要
弹性薄板弯曲是我们在制造过程中遇到的最常见的问题,为使问题简单化,便于理解,我们用有限元法分析薄析问题,用薄板的单元组成来取代原来的薄板,通常采用本角形和矩形薄板单元的组合代替壳体,由平面应力和弯曲应力状态加以组合得到薄板的应力状态。采用三角形单元,并将每一单元作为相应的平面应力单元和薄板弯曲单元的线性组合,介绍此类薄板弯曲问题的有限元法。
Plate bending is the most common problem in manufacturing. This article describes the solution to plate bending problems with the finite element method. The sheet modules are used to replace the original sheet to get the stress state of sheet metal by combining the state of plane stress with that of bending stress.
