摘　　要：This research introduced the design,analysis and optimization of bionic shrimp chela multi-cell tubes(BSCMTs)in bending by embedding an arthropod's microstructure inside a thin-walled square structure.A three-point impact bending finite element model was,in the first instance,correlated with physical tests and then modified to assess the energy absorption performance of bionic multi-cell tubes considering initial peak force,specific energy absorption and mean crushing force.Following a complex proportional assessment(COPRAS)approach and optimization phases,results demonstrated that the BSCMT with a W-shape section had the best energy absorption characteristics and should be considered in future as a possible contender for vehicle B-pillar structures that are subjected to bending and require excellent energy absorption properties to protect the occupants in high-speed impact collisions.
