Experimental observation on the results of stress to outside hit on fresh skull by electromotive method

Objective To observe the results of stress of the fresh skull to hit from outside.Methods Homemade experimental set of skull was used and the impact of hit on the fresh skull was observed,On he surface of the skull,stick twenty-two right-angle strain pieces on the left and right forehead,the left and right coping,the left and right temporal bone,and the occiput of the skull,knock separately on the forehead-pole,the left and right forehead,the left and right coping,the left and right temporal bone,and the occiput of the skull with 100N forces.test the stress distributing of the skull with electromotive method.Results The magnitude and direction of 1st principle stress of the surface of the skull was obtained by analytic theory of experimental stress.Conclusion The experiment can provide definite gist to precisely diagnose the damage and fracture of bumped skull.
