Mechanical Models and Finite-Element Approaches for the Structural Analysis of Photovoltaic Composite Structures: a Comparative Study
- 116 Downloads
In general, photovoltaic composite structures are three-layer laminates with a thin soft core layer. Due to the high contrast between the mechanical properties of skin and core layers, such structures have been studied by different theories. Finite-element models, continuum-based theories, and two-dimensional plate/shell theories are used in the analysis of laminated structures. The present study deals with the modeling and computational simulation of photovoltaic modules in the context of global structural mechanics. The focus is on the implementation of different elements in both two- and three-dimensional approaches to find the most efficient one for analyzing photovoltaic composite structures.
