Meaningful finite element discretization scheme: a case for circular disk subjected to four radial loads

In finite element (FE) modelling, apart from proper element selection, selection of an appropriate discretization scheme is crucial in correctly evaluating the intended variables. Photoelasticity plays an effective role in selecting an appropriate discretization scheme for modelling problems in stress analysis. A meaningful FE discretization is very important in evaluating the desired parameters in FE analysis. The adaptive mesh refinement emphasizes the need for a meaningful discretization of domain. This paper presents a discretization strategy for meaningful discretization of the circular disk subjected to four equal radial loads. The work evolved the generation of software for the disk subjected to four radial loads perpendicular to each other. Due to symmetry of the problem only quarter of the disk is discretized.
