“…), and/or ball-joint systems used in space grid technologies awaits attention. Future work is also needed with regards to the experimental testing of real-scale PMBS, the multiscale modeling of viscoelasticity, plasticity, fracture and damage, nonhomogeneous and nonlocal response [33]- [47], as well as the inclusion of prestressed cables in PMBs [48] [49], made, e.g., of shape memory alloys, in order to increase the dissipation and re-centering capacities of the device [18], [24]. Future studies will also investigate shell-like generalizations the systems examined in the present work [43]- [49], the insertion of struts with different response in tension and compression within pentamode lattices [50]- [54], and the fabrication and testing of physical models through innovative manufacturing techniques [55]- [58].…”
