In the Received 6 January 2015 present study the dynamic response of a punch to the head of a Wushu fighter was simulated Accepted 5 May 2015 by modeling the human head in ABAQUS software. Moreover the maximum displacement Available online and the stress distribution in the helmet and head parts were analyzed by finite elements 6 May 2015 Keywords method. The obtained results showed a significant interval in the response of different tissues Finite element analysis to the delivered blow. The maximum shear stress normal stress and displacement in the helmet Shear stress were MPa MPa and mm respectively while these magnitudes were Punch respectively MPa MPa and mm in skull MPa MPa and Sanda protective helmet mm in the head skin and MPa MPa and mm in brain. The present model with its unique features can be a valuable and powerful instrument to gain a better insight into the injury mechanism for better .
