Viscoelastic Fractional Model with a Non-Uniform Time Discretization for Laminated Glass: Experimental Validation

Challenging Glass Conference Proceedings
We discuss a novel approach, based on fractional calculus with a non-uniform time discretization, to numerically simulate interlayer viscoelastic behaviour and associated time-dependent deformation of laminated glass.

Time-Stepping Error Estimates of Linearized Grünwald–Letnikov Difference Schemes for Strongly Nonlinear Time-Fractional Parabolic Problems

Fractal and Fractional
A fully discrete scheme is proposed for numerically solving the strongly nonlinear time-fractional parabolic problems. Time discretization is achieved by using the Grünwald–Letnikov (G–L) method and some linearized techniques, and spatial discretization ...

Study of fractional telegraph equation via Shehu homotopy perturbation method

Open Physics
The iterative Shehu transform homotopy perturbation method (HPM) is used in the present research to address fractional telegraph equations in different dimensions, respectively. Considered equations particularly stand out in the field of material science

Discretization of the Caputo time-fractional advection-diffusion problems with certain wavelet basis function

Journal of Nigerian Society of Physical Sciences
Considering the new wavelet-based Galerkin finite element technique constructed with Iweobodo-Mamadu-Njoseh wavelet (IMNW) as the basis function in seeking the numerical solution of time-fractional advection-diffusion equations (TFADE), the TFADE must ...

Spectral element discretization of the time-dependent Stokes problem with nonstandard boundary conditions

Boundary Value Problems
This work deals with the spectral element discretization of the time-dependent Stokes problem in two- and three-dimensional domains. The boundary condition is defined on the normal component of the velocity and the tangential components of the vorticity.

Implementation of the spectral element discretization of the nonstationary velocity–vorticity–pressure Stokes formulation

Boundary Value Problems
This paper deals with the resolution of the time-dependent velocity–vorticity–pressure formulation of Stokes problem in a two- and three-dimensional domain. The discretization is based on the spectral element method with respect to the space variable and
