Hole Geometry

The presence of holes in composite plates subjected to a uniform heat flux induces thermal stresses. Hole geometry is one of the important parameters in the stress distribution in perforated composite plates. In this study, using the two-dimensional thermoelastic theory, and on the basis of the Lekhnitskii' complex variable technique in steady-state condition, stress distribution around holes with different shapes in an infinite composite plate under uniform heat flux is investigated. Using a conformal mapping function, the thermal stress analysis of an infinite plate with a circular hole under a uniform heat flux is developed to analyze the plate containing a noncircular hole. The perforated composite plate is under a uniform heat flux at infinity and Neumann boundary conditions and thermal-insulated condition at the edge of the hole are considered. The rotation angle of the hole, fiber angle, the flux angle, and bluntness are important parameters investigated in the present study. In addition, the optimal values of the effective parameters to achieve the lowest thermal stress around different holes have been reported for several different materials. The obtained results show that these parameters have a significant effect on the stress and displacement distributions around the rectangular hole.
