Research on a Touch on the Stress Model

Abstract:

An impact event is a complex phenomenon that includes the interaction between projectile and structure, motion of the projectile and the dynamics of the structure. Complete modeling of an impact event can always be done using a 3D finite element model, The Finite Element Model(FEM) approach is often very costly both from modeling and calculation duration point of views, so it can be simplified by using simplified impact models, It can be used for the estimation of the contact force history. In this paper, firstly, analyze the current situation of the study of the collision of the home and abroad , secondly, Ocean Bottom Seismometer(OBS) whereabouts and hit the bottom are analyzed in detail, and finally come to the impact solution formulas.
