Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Geometric regularity criteria and inviscid limit of incompressible Navier--Stokes Equations under Navier boundary condition
Navier边界条件 不可压缩 Navier-Stokes方程 几何正则性准则 无粘极限
2023/11/29
We report our recent works on the analysis of 3D incompressible Navier--Stokes Equations subject to the Navier slip boundary condition, i.e., tangential components of the stress exerted by the normal ...
Geometric and material nonlinear analysis of tensegrity structures
Nonlinear analysis Tensegrity structures Geometric nonlinearity Material nonlinearity Large displacements
2012/2/28
A numerical method is presented for the large deflection in elastic analysis of tensegrity structures including both geometric and material onlinearities. The geometric nonlinearity is considered base...
Geometric nonlinear dynamic analysis of curved beams using curved beam element
Curved beam element Geometric nonlinear formulation Rigid-flexible coupling
2012/2/28
Instead of using the previous straight beam element to approximate the curved beam, in this paper, a curvilinear coordinate is employed to describe the deformations,and a new curved beam element is pr...
