STUDY ON DYNAMIC RESPONSE AND ENERGY ABSORBING CHARACTERISTICS OF SHALLOW SPHERICAL SHELLS UNDER IMPACT LOADS

Ma Chunsheng,Du Huiliang,Zhang Jinhuan,Huang Shilin(State Key Laboratory of Automotive Safety and Energy,Department of Automotive Engineering,Tsinghua University,Beijing 100084)  
Dynamic response and energy absorbing characteristics of shallow spherical shell structures when impacting a rigid plate are studied here.Axial impact experiments of an aluminum shallow spherical shell with radius to thickness ratio(R/t) greater than 250 are conducted.The approximate formulae of impact loads versus compression displacement and initial velocity versus max displacement are derived by using the large deformation thin shell and plastic hinge theory based on the law of energy conservations.The analysis results agree with the experimental results well and can meet requirements of engineering practices.
