Theoretical analysis yields equations for transverse deflection of, and stresses in, rectangular membrane subject to transverse pressure load and to tensile preloads applied uniformly along edges. This is extension of analysis reported in "Deflection and Stress in Preloaded Square Membrane" (GSC-13367).
Theoretical analysis yields equations for transverse deflection of, and stresses in, square membrane subject to both uniform transverse load and tension preloads applied uniformly along the edges. Follows energy/virtual-displacement approach. Basic equation expresses strain energy in membrane as double integral, over x and y coordinates of square, of function of longitudinal strains, shear strain, thickness of membrane, and Young's modulus and Poissons's ratio of membrane material.
