Metallic mesh is a key component of Large Deployable Reflectors for telecommunication and Earth observation spacecraft antennas. Deep knowledge of mesh structural characteristics and the possibility to numerically simulate its behaviour are mandatory steps for its correct use in the reflectors. The mesh is strongly compliant and anisotropic; hence, a specific testing machine has been designed and built, able to stretch the specimen along two directions, with uncoupled motion laws, controlled both in force and displacement. The mechanical characterization is driven so that a numerical simulation of the mesh is derived requiring only common finite element formulations.

Abstract
Metallic mesh is a key component of Large Deployable Reflectors for telecommunication and Earth observation spacecraft antennas. Deep knowledge of mesh structural characteristics and the possibility to numerically simulate its behaviour are mandatory steps for its correct use in the reflectors. The mesh is strongly compliant and anisotropic; hence, a specific testing machine has been designed and built, able to stretch the specimen along two directions, with uncoupled motion laws, controlled both in force and displacement. The mechanical characterization is driven so that a numerical simulation of the mesh is derived requiring only common finite element formulations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
