| Abstract: |
In this paper, Riemann-Liouville fractional model with nonuniform time steps is presented to simulate the process of metal-laser drilling to overcome the initial singularity. In addition, two distinct operators conformable fractional derivatives, and Caputo-Fabrizio are applied. The spatial derivatives are approximated by the radial point interpolation method. The simulation results of Riemann-Liouville show significant improvement in the agreement with experimental data and the simulation results. |
