Virtual Element Formulation for Finite Strain Elastodynamics [PDF]

Computer Modeling in Engineering & Sciences, 2021
The virtual element method (VEM) can be seen as an extension of the classical finite element method (FEM) based on Galerkin projection. It allows meshes with highly irregular shaped elements, including concave shapes. So far the virtual element method has been applied to various engineering problems such as elasto-plasticity, multiphysics, damage and ...

Virtual Elements on polyhedra with a curved face

Bulletin of Mathematical Sciences, 2023
We revisit classical Virtual Element approximations on polygonal and polyhedral decompositions. We also recall the treatment proposed for dealing with decompositions into polygons with curved edges.

The virtual element method

Acta Numerica, 2023
The present review paper has several objectives. Its primary aim is to give an idea of the general features of virtual element methods (VEMs), which were introduced about a decade ago in the field of numerical methods for partial differential equations, in order to allow decompositions of the computational domain into polygons or polyhedra of a very ...

A virtual element formulation for general element shapes [PDF]

Computational Mechanics, 2020
AbstractThe virtual element method is a lively field of research, in which considerable progress has been made during the last decade and applied to many problems in physics and engineering. The method allows ansatz function of arbitrary polynomial degree. However, one of the prerequisite of the formulation is that the element edges have to bestraight.

Virtual Reconstruction-Based Robust Adaptive Beamforming for Distributed Digital Subarray Antennas

International Journal of Antennas and Propagation, 2021
For the distributed digital subarray antennas (DDSA), the conventional beamforming may give rise to grating lobes, high sidelobes, and other problems. In this paper, the gaps between the subarrays are filled with virtual array elements, and then the DDSA
