The Effect on Thermal and Residual Stresses of Parabolic Temperature Loading in a Thermoplastic Composite Disc

Abstract

The aim of this study was to investigate of the effect on thermal and residual stresses of parabolic temperature loading in a thermoplastic composite disc. It was reinforced by steel-fibers as unidirectional for radial direction. The finite element method (FEM) was used to estimate the thermal elastic, elasto-plastic, and also the residual stress distributions in the selected model of the composite disc. Consequently, the thermal stress analysis was carried out using ANSYS finite element software. The temperature loading was selected to vary parabolically from inner surface to outer surface along the radial sections. Different values of it were effected in the disc model. Thermal loading was chosen from 80°C to 120°C. Because of the composite disc having different thermal expansions in radial and tangential directions, thermal stresses were produced in it by the applied thermal loadings. The values of the tangential stress components both elastic and elasto-plastic solutions were higher than the radial stress components. Besides, the residual stress components were calculated using elastic and elasto-plastic solution results. The results obtained showed that the magnitude of thermal and residual stresses considerably increased parabolic temperature loadings.

Investigation of Radial and Tangential Stresses Occurring in Epoxy (T300) Material Disc with Different Methods

“…In a different study, the calculated stresses on a disk with different mechanical properties were analyzed. Similarly, it has been found that the tangential stress is maximum in the innermost part of the disk and minimum in the outermost region [23] . In addition, it is believed that the results obtained by numerical analysis, a computer program, and the results obtained in Tables 2 and 3 above are quite close to the results obtained by the Chebsey method, which generally indicates that the results are correct.…”

Thermo-mechanical stress analysis of rotating fiber reinforced variable thickness disk

“…Tabulated properties belong to glass fibers and epoxy resin. Subsequently, using the equations ( 2) to ( 9) and ( 45) to (48), composite properties are found. Also, throughout this subsection, following geometric dimensions are used: h a = 0.04 m, a = 0.04 m, and b = 0.10 m. In order to have a convex thickness profile, geometric parameter is set as n = 20.6.…”

“…Sayer et al 46 have carried out analytical and experimental solutions to analyze thermoelastic stresses in a fiber reinforced thermoplastic composite disk. Elastic-plastic stresses of a pressurized composite disk, which constituents metal fibers and aluminum matrix, under thermal loads are studied by Topcu et al 47 The examination of Sen 48 focused on the influence of thermal and residual stresses on composite thermoplastic disks.…”

Thermal Residual Stresses in Thermoplastic Composite Disc with Holes Using 3D-Fem

“…It was found these two solutions are in good agreement. Sen [9] investigated the effect on thermal and residual stresses of parabolic temperature loading in a thermoplastic composite disc. FEM was used to estimate the thermal elastic, elasto-plastic, and also the residual stress distributions in the selected model of the composite disc using ANSYS.…”
