| Abstract: | The
aim of this investigation is to observe the influence of multiple holes on
thermal stresses in a thermoplastic composite hollow disc. For this purpose, a
thermoplastic composite disc is reinforced by steel fibers as curvilinear for
radial direction, and thermal loads are carried out for uniform distribution at
various temperatures. The solution is completed in two parts that are elastic
and elastic-plastic analysis. Additionally, residual stresses are calculated
using these analysis results. Finite element method (FEM) is utilized for
calculation of thermal stresses. Therefore, the thermal stress analysis is performed
using ANSYS® finite element software. Due to the fact that composite
disc have different thermal expansions in radial and tangential directions,
thermal stresses are taken place in disc by the applied uniform thermal
loadings. The magnitude of the tangential stress components both elastic and
elastic-plastic solutions is higher than that of the radial stress components,
except edges of multiple holes. The present study concludes that magnitudes and
distributions of thermal and residual stresses on the composite disc are
considerably affected by increasing the uniform temperature loadings and
existence of multiple holes |
