Abstract:

In the article are considered the results of a numerical investigation of the mode of deformation of models of composed mesh aluminum shells of variable curvature. From the carried out on models studies under the action of a uniformly distributed static load is clear that the shell behaviors as a compressed structure with a high load capacity and confirmed the position that the load, uniformly distributed over the covering, is determinative by the shell’s deformations. The numerical calculation of mesh shells models meshd in elastic stage showed good agreement between calculated and experimental results. The study showed that the characteristic form of failure is the loss of loadcarrying capacity related with changes in the geometry of membranes at very high loads.

Keywords: single-mesh shell; variable curvature; static calculation.
