Simultaneous optimization of topology and layout of modular stiffeners on shells and plates

Abstract Stiffened shells and plates are widely used in engineering. Their performance is highly influenced by the arrangement, or layout, of stiffeners on base shell plate geometric features, topology, these stiffeners. Moreover, modular design beneficial, since it allows for increased quality control mass production. In this work, a method developed that simultaneously optimizes topology their layout plate. This accomplished introducing fixed number stiffeners, which subject to density-based optimization mapping modules ground structure. To illustrate potential applications, several stiffened examples presented. All demonstrated proposed able generate clear topologies any distinct
