Abstract: Currently, transformable rod systems have found wide application in the designs of spacecraft panels and as various stents in medicine. It is of some theoretical interest to extent the idea of geometric variability to spatial rod systems of complex shape. The concept of kinematic shaping of a regular rod system from a flat to a domed position is proposed. The finite element method in combination with the modified Lagrange method was used for numerical implementation of this concept. To assess the level of deformed state of the rods of a modular lattice, an energy criterion is proposed that allows determining the most loaded rods considering genetic nonlinearity of the system.
