Finite element simulations of ballistic impact on monolithic glass

초록

The monolithic glass, without damage, subjected to ballistic impact, is studied by the use of thecoded finite element program. To analyze the impact response of monolithic glass like ordinary annealedglass and tempered glass, a finite element approach based on the Hertzian contact law and Sun'shigher-order beam finite element is proposed. For verifying effectiveness of this finite element program,the contact force history is analyzed in conjunction with the loading and unloading processes. And, also,the time history of the impact responses such as the strain and stress according to the thickness changesdue to transverse impact at the center are calculated.
