RESEARCH OF FREE-EDGE EFFECT OF COMPOSITE LAMINATES BASED ON SEPARABLE HAMILTON CANONICAL EQUATION

Jixie qiangdu, 2018
A semi-analytical solution theory is presented by combining the separable Hamilton canonical equation and finite element method. The problem of free-edge effect of orthotropic laminates is studied in symplectic system.

An unfitted Nitsche method for incompressible fluid-structure interaction using overlapping meshes [PDF]

, 2014
We consider the extension of the Nitsche method to the case of fluid–structure interaction problems on unfitted meshes. We give a stability analysis for the space semi-discretized problem and show how this estimate may be used to derive optimal error ...
