Large Deflection Analysis for a Plate Strip Subjected to Normal Pressure and Heating

Abstract

Abstract Large deflection analysis is carried out to determine the deflections and membrane stresses for an infinite strip when subjected to pressure and temperature variations across the width of the strip with the end points fixed in space. Results are graphed for both clamped and simply supported edge conditions in the case of uniform temperature T0, and uniform pressure p0. The calculations also include the possible thermal buckling deflections. In the limit case of a membrane of width b and thickness h, subjected to this loading condition, the central deflection w0 is determined from the simple relation [ ( w 0 / h ) 2 - 3 8 ( 1 + ν ) ( b / h ) 2 α T 0 ] ( w 0 / h ) = p 0 b 4 / ( 256 D h )
