Based on the additional decomposition theorem of deformation gradient (i. e. S-R theorem) and co-moving coordinate technique,a typical nonlinear mechanical problem, contact large deformation of rubber ring radially compressed, was computed by FEM.
A FEM three-dimension model of windshield is established, based on the contact-impact finite element procedures. Rate constitiutive models of windshield material are adapted with failure models. The dynamic process of bird striking windshield is simulated.
The set FEM for structure uncertainty analysis, which could be used to solve the reliability problems with less uncertain information data and without statistical characteristics of parameter probability, is presented and is available for analysing large scale complex structures.
The influence of different Passion ratio values on the apparent elastic modulus is also examined,and the validity of this homogenization model in uniaxial tension is approved by the finite element method.
An FEM approximation for a fourth-order variational inequality of second kind
By using regularization method, the original problem can be formulated as a differentiable variational equation, and the corresponding discrete FEM variational equation is presented afterwards.
IBC/FEM Analysis of Electromagnetic Scatter of Cavities Coated with Layered Medium
The Leontovich impedance boundary condition (IBC) is combined with the edge-based finite element method (FEM) in this paper to analyze the electromagnetic (EM) scattering of cavities coated with a multilayered dielectric.
Numerical results are presented, which demonstrate that the presented IBC/FEM approach is accurate and convenient for the analysis of EM scattering of open-ended cavities coated with the dielectric.
