Adaptive energy-dissipative structure. (a) Using three double-spirals with different thicknesses to develop low, medium, high, and adaptive stiffness energy-dissipative structures. (b) Force–displacement graphs resulted from experimental tensile tests conducted on the four developed structures at a rate of 1 mm/s. (c) Comparing the amount of dissipated energy resulting from the deformation of four developed structures when subjected to the same tensile forces at a rate of 1 mm/s.
