Abstract
In this thesis, current problems in the usage of composites in a myriad of applications are reviewed. The difficulties in the industry due to absence of data for long-term use of composites are put forward. The method acting as a solution to this issue called the asymptotic homogenization method is established, and the current literature available on this method is further elaborated. Then, the mathematical equations used to predict these long-term properties of the composites are illustrated. Further, parametric inputs are given to those equations, and the variation of the properties along the thickness of the structures is represented. The aim is to calculate effective properties for a myriad of structures with different combinations of material and dimensional parameters to encourage the use of composites more spontaneously. The results are illustrated graphically. Applications are put forth for the structures with resemblance to the behavior and comparison to specific mechanical properties.
Description
The parametric analysis of various composite structures with different types of reinforcing elements is conducted in this thesis. The parametric analysis is considered by considering some materials suitable for the application and assuming realistic dimensions to the composite plate or shell. The aim is to calculate the effective properties of coefficients for a wide range of composites and provide valuable real-life usage data. These coefficients are calculated by use of the equations obtained using the asymptotic homogenisation method. The thickness of any other required dimension of the composite structure is varied for the same material properties, and the effective coefficients are calculated for each of the varying dimensions. This provides huge amounts of data and statistics to encourage the use of composites in more layman applications instead of them already being used in high-tech applications. The results are represented graphically and discussed in terms of the dimensional changes and material property variation. Optimization of the results is also carried out by tweaking the input parameters to obtain the best possible combination of properties from these composite structures.
