A Closed-Form Solution for Two-Dimensional Diffusion Equation Using Crank-Nicolson Finite Difference Method

Iman Shojaei; Hossein Rahami

Volume 51, Issue 1 , June 2019, , Pages 71-77

https://doi.org/10.22059/jac.2019.71297

Abstract
  In this paper a finite difference method for solving 2-dimensional diffusion equation is presented. The method employs Crank-Nicolson scheme to improve finite difference formulation and its convergence and stability. The obtained solution will be a recursive formula in each step of which a system of ...  Read More

Vibration Analysis of Global Near-regular Mechanical Systems

Iman Shojaei; Hossein Rahami

Volume 49, Issue 2 , December 2017, , Pages 113-118

https://doi.org/10.22059/jac.2017.7983

Abstract
  Some near-regular mechanical systems involve global deviations from their corresponding regular system. Despite extensive research on vibration analysis (eigensolution) of regular and local near-regular mechanical systems, the literature on vibration analysis of global near-regular mechanical systems ...  Read More
