Abstract
This paper presents a meaningful discretization scheme for asymmetric object, such as rail section for central loading. Finite element (FE) plane stress analysis of the problem is carried out. The results from FE analysis are post processed to simulate the photoelastic experiment and check the discretization scheme. Issues related to experimental limitation of desired loading and their specification as boundary condition in finite element modeling are discussed
