International Journal for Numerical Methods in Engineering, Volume 125, Issue 21, 15 November 2024.Abstract Imposing nonperiodic boundary conditions for unit cell analyses may be necessary for a number of reasons in applications, for example, for validation purposes and specific computational setups. The work at hand discusses a strategy for utilizing the powerful technology behind fast Fourier transform (FFT)‐based computational micromechanics ...

Superconvergence Analysis of Finite Element Method for a Second-Type Variational Inequality
Journal of Applied Mathematics, 2012 This paper studies the finite element (FE) approximation to a second-type variational inequality. The supe rclose and superconvergence results are obtained for conforming bilinear FE and nonconforming EQrot FE schemes under a reasonable regularity of the

Journal of Inequalities and Applications, 2019 In this paper, we investigate a variational discretization approximation of parabolic bilinear optimal control problems with control constraints. For the state and co-state variables, triangular linear finite element and difference methods are used for ...
