k-Version of Finite Element Method for BVPs and IVPs
Mathematics, 2021 The paper presents k-version of the finite element method for boundary value problems (BVPs) and initial value problems (IVPs) in which global differentiability of approximations is always the result of the union of local approximations. The higher order

Higher Order Cut Finite Elements for the Wave Equation [PDF]
Journal of Scientific Computing, 2019 The scalar wave equation is solved using higher order immersed finite elements. We demonstrate that higher order convergence can be obtained. Small cuts with the background mesh are stabilized by adding penalty terms to the weak formulation. This ensures that the condition numbers of the mass and stiffness matrix are independent of how the boundary ...

Bending and free vibration of functionally graded beams using various higher-order shear deformation beam theories [PDF]
, 2012 In this paper, various higher-order shear deformation beam theories for bending and free vibration of functionally graded beams are developed. The developed theories account for higher-order variation of transverse shear strain through the depth of the ...

Elastic pantographic 2D lattices: a numerical analysis on the static response and wave propagation; pp. 219–225 [PDF]
Proceedings of the Estonian Academy of Sciences, 2015 In the present paper we consider a structure constituted by âlongâ Euler beams forming two mutually intersecting arrays and interacting via internal pivots, which we call pantographic 2D lattices.
