Abstract:
Objective To investigate the mechanical properties and distributing characteristics of human fresh ulnar compact and its correlation to strain rate.Methods Impact compressive experiment for human fresh ulnar compact bone at high strain rate =1.2?10~(3)/s by Split Hopkinson Pressure Bars(SHPB) were performed.Results The mechanical properties of human fresh ulnar compact bone varied along the longitudinal direction,the ultimate stress,breaking strain and dynamic compressive modulus at middle section were stronger than those at both ends,the strongest at section occurs nearly at the junction of proximal and middle thirds and the properties at the proximal end were much higher than those at the distal end.The ultimate stress at high strain rate was largely dependent on strain rate.Conclusion Under impact compression,the ulnar compact gets fractured easily at both ends,especially at distance section.
