One-Dimensional Numerical Methods For Static And Dynamic Analysis Of Thin-Wallwd Beams With Open Profile

Thin-walled beams are widely used in spaceflight, building and bridge construction, ship design and mechanism. Therefore, it is more important to do the research within the aspect of numerical algorithms in this area. This paper introduces the special solved ways and the significant feature of the thin-walled beams when they are on the load. According to these, and also based on vlasov theory, the numerical algorithms of static analysis and dynamic analysis of the thin-walled beams are developed.In this paper, there are two numerical analyses methods that are developed based on vlasov theory. One is one-dimensional discrete finite member element method, which is based on finite member element method; and the other one is spline Rize method which is based on spline function. These two methods are applied to the static analysis of restrict torsion of thin-walled beams separately and then compare their results between each other. One-dimensional discrete finite member element method which is based on Hamilton Theory is applied on the theoretical and numerical dynamic analysis of the open section thin-walled beams. At last, there is a C...
