A Cº Interior Penalty Method for 4th order PDEs
, 2020 A method to solve 4th-order PDEs using the Finite Element Method (FEM) with standard Cº elements is derived and studied. It is based on a special weak form accounting for the discontinuous derivatives of the approximation and imposing their normal ...

Variational analysis for simulating free‐surface flows in a porous medium
Journal of Applied Mathematics, Volume 2003, Issue 8, Page 377-396, 2003., 2003 A variational formulation has been developed to solve a parabolic partial differential equation describing free‐surface flows in a porous medium. The variational finite element method is used to obtain a discrete form of equations for a two‐dimensional domain.

An efficient scheme for numerical solution of Burgers’ equation using quintic Hermite interpolating polynomials [PDF]
, 2015 A numerical scheme combining the features of quintic Hermite interpolating polynomials and orthogonal collocation method has been presented to solve the well-known non-linear Burgers’ equation. The quintic Hermite collocation method (QHCM) solves the non-

A frictionless contact problem for viscoelastic materials
Journal of Applied Mathematics, Volume 2, Issue 1, Page 1-21, 2002., 2002 We consider a mathematical model which describes the contact between a deformable body and an obstacle, the so‐called foundation. The body is assumed to have a viscoelastic behavior that we model with the Kelvin‐Voigt constitutive law. The contact is frictionless and is modeled with the well‐known Signorini condition in a form with a zero gap function.

Hot‐pressing process modeling for medium density fiberboard (MDF)
International Journal of Mathematics and Mathematical Sciences, Volume 26, Issue 12, Page 713-729, 2001., 2001 We present a numerical solution for the mathematical modeling of the hot‐pressing process applied to medium density fiberboard. The model is based on the work of Humphrey (1982), Humphrey and Bolton (1989), and Carvalho and Costa (1998) with some modifications and extensions in order to take into account mainly the convective effects on the phase ...

On the existence of solutions of strongly damped nonlinear wave equations
International Journal of Mathematics and Mathematical Sciences, Volume 23, Issue 6, Page 369-382, 2000., 2000 We investigate the existence and uniqueness of solutions of the following equation of hyperbolic type with a strong dissipation: utt(t,x)−(α+β(∫Ω|∇u(t,y)|2dy)γ)Δu(t,x) −λΔut(t,x)+μ|u(t,x)|q−1u(t,x)=00, x∈Ω,t≥ u(0,x)=u0(x), ut(0,x)=u1(x), x∈Ω, u|∂Ω=0 , where q > 1, λ > 0, μ ∈ ℝ, α, β ≥ 0, α + β > 0, and Δ is the Laplacian in ℝN.

Finite difference approximations for a class of non‐local parabolic equations
International Journal of Mathematics and Mathematical Sciences, Volume 20, Issue 1, Page 147-163, 1997., 1997 In this paper we study finite difference procedures for a class of parabolic equations with non‐local boundary condition. The semi‐implicit and fully implicit backward Euler schemes are studied. It is proved that both schemes preserve the maximum principle and monotonicity of the solution of the original equation, and fully‐implicit scheme also ...

International Journal of Stochastic Analysis, Volume 5, Issue 1, Page 19-27, 1992., 1991 Existence and uniqueness are proved for nonlocal (in time) for solutions of linear parabolic partial differential equations. Instead of an initial condition, there is a relation connecting the initial value to values of the solution at other times. L2 error estimates are obtained for the semidiscrete approximation of the problem using finite elements ...
