- Abstract:
- In this research it is aimed to have an investigation on the thermo-mechanical analysis of functionally graded skew plates. In order to analyze the behavior of the skew FGM plates, a constant pressure load as a mechanical load is distributed through the plate. Also the thermo-mechanical load is a combination of this mechanical load and a temperature gradient in upper and lower surface applied as in-phase . Various boundary conditions considered in analysis are combination of simply support and clamped edges including CCCS, CCSS, CCCC. The analysis are based on CPT and the Von-Karman theory is used in the solution. The graded materials are distributed through the thickness according to P-FGM and S-FGM functions. Results of P-FGM and S-FGM distributions are compared in the same boundary conditions and mechanical or thermo-mechanical loadings. Also the effect of geometrical characteristics of the plate and temperature change has been analyzed. The results of skew plate has been compared with a rectangular plate. It seems the skew plates are a good substitution to the rectangular plates according to resulted stress in the thickness direction of the plate. through the plate.
