Elastic　metamaterials　with　locally　resonant　components　exhibit　unique　band-gap　behavior　that　can　be　applied　to　control　wave　propagation　in　flexural　beams.　Previous　studies　mainly　emphasized　the　utilization　of　transversal　deformations　of　flexural　beams.　A　novel　metamaterial　configuration　is　presented　in　this　work;　in　particular,　to　obtain　a　wide　band　gap　in　low-frequency　ranges　with　reduced　expenses　in　associated　mass,　inerter-based　resonators　and　cantilevered　deformations　caused　by　the　rotation　of　flexural　beams　are　combined.　The　study　is　performed　by　using　an　analytical　approach　based　on　the　finite　element　(FE)　method　and　the　Floquet-Bloch　theorem.　Both　the　wavenumber-frequency　and　the　damping　ratio-frequency　relationships　and　relevant　band　structures　are　set.　These　two　types　of　band　structures　are　further　considered　for　the　investigation　of　the　effects　of　various　system　parameters　on　the　band-gap　behavior　and　wave　attenuation　performance　in　the　whole　frequency　range.　Finally,　the　effectiveness　of　the　proposed　concept　is　validated　by　means　of　numerical　examples.
