Abstract
In this paper, a nonlinear numerical analysis using the Finite Element Method and experimental verifications are performed for shells loaded with concentrated forces. The analysis took into account both the large displacements of the application points of forces and the physical nonlinearity of the material. The Finite Element analysis yielded supplementary information about the distribution of stresses, a task difficult to accomplish with experimental procedures.
