Abstract
In this paper, a finite point method (FPM) is developed and adopted for solving the chloride diffusion equation for prediction of service life of concrete structures and initiation time of corrosion of reinforcements. Diffusion of chloride ions is generally assumed to follow the Fick’s second law. FPM is a truly meshless method which uses a moving least square approximation within a collocation strong form for solving the governing differential equation. Several 1D and 2D problems are solved using FPM and the results are compared with the analytical solution, classical finite element and finite difference methods, and weak form meshless based element free Galerkin method.
