Numerical solution of Atangana–Baleanu–Caputo time-space fractional diffusion equation

Arab Journal of Basic and Applied Sciences, 2022
In this article, the time-space fractional diffusion equation is solved by using the fractional operator in Atangana–Baleanu–Caputo (ABC) sense based on the Mittag-Leffler function involving non-singular and non-local kernels.

An 8-Node Solid-Shell Finite Element based on Assumed Bending ‎Strains and Cell-Based Smoothed Membrane Strains for Static Analysis of Plates and Shells [PDF]

Journal of Applied and Computational Mechanics, 2020
In this paper, a new 8-node solid-shell finite element is proposed. The transverse shear strains and transverse normal strains of the element are separately interpolated and related to the C0-displacement approximation at tying points to overcome the ...

Exponentially Convergent Trapezoidal Rules to Approximate Fractional Powers of Operators

Journal of Scientific Computing, 2022
AbstractIn this paper we are interested in the approximation of fractional powers of self-adjoint positive operators. Starting from the integral representation of the operators, we apply the trapezoidal rule combined with a double-exponential transform of the integrand function.
