INFLUENCE OF THE CHANGE OF IMPACT VELOCITY ON IMPACT DEFORMATION FIELD OF METEORITE
撞击速度的变化对陨石撞击形变场的影响及其规律探讨

Aiming to meteorite impact affair of Cangshan,the popular nonlinear program ANSYS/LS-DYNA is used to analyze how the change of impact velocity affect the emergence,development and evolvement of the impact deformation field of meteorite. The relationship curves between impact velocity and deformation field are obtained,which can be an important base of the research for meteorite impact.
