Before revision: Given the Studying the problem of a hemispherical membrane in a gravitational field, it can be demonstrated that the membrane undergoes compressive stress in its upper part, while it is subjected to hoop tensile stresses in the lower part (under 52° from vertical axis of symmetry).
