Scientific paper

A finite element solution for the structural behavior of a scientific balloon has been obtained using a non-linear finite element code. The pneumatic skin is modelled by shell elements that are given a small artificial bending stiffness to overcome numerical problems yet the membrane solution remains unaffected. Validation of the analysis approach is provided through strain measurements on a small scale balloon that exhibits all essential features of a full scale balloon.
