Abstract
In this study, a thermal stress analysis was evaluated on symmetric angle-ply laminated thermoplastic composite plates that were having different square hole dimensions. The temperature loading was selected uniformly. Besides, it was applied with various values that were chosen as 50, 60, 70, 80, 90, 100 °C, because of the fact that the effect of increasing uniform temperature on thermal stresses was examined. The width plate-to-the width square hole, a/b, ratios were changed as 2, and 4. Thermoplastic laminated composite plates were assumed to be simple supported. Laminated plates were composed of four orthotropic layers oriented with angle-ply in symmetric manner. The solution was carried out by using ANSYS finite element program. The results were showed in figures depending on applied temperatures, orientations and dimensions of square hole.
Highlights
Availability of the new, low cost, high performance fiber reinforced plastic (FRP) structural composites for infrastructure construction and rehabilitation has given an impetus to the development of a new technology in construction industry
The width of square laminated plate was assumed as 200 mm, whereas the widths of square hole were selected as 100 and 50 mm for Model 1 and Model 2, respectively
The thermal stress distributions are changed throughout the thickness of laminated plate, stress distributions are obtained as same both top and bottom surfaces of the composite plate because of the symmetric orientation
Summary
Availability of the new, low cost, high performance fiber reinforced plastic (FRP) structural composites for infrastructure construction and rehabilitation has given an impetus to the development of a new technology in construction industry. Senel et al [5], were performed residual stress analysis of laminated composite plates under thermal loads and they used analytical methods. Shabana and Noda [6] have investigated elasto-plastic thermal stresses in a rectangular plate of a particle reinforced composite functionally graded materials were treated by finite element method. In their analysis, the thermal stress constitutive equation of a particle-reinforced composite taking temperature change and damage process into consideration was used. Sayman et al [7], a thermal elastic-plastic stress analysis was carried out on a steel fiber high-density polyethylene matrix composite beam.
