초록
The monolithic glass, without damage, subjected to ballistic impact, is studied by the use of the coded finite element program. To analyze the impact response of monolithic glass like ordinary annealed glass and tempered glass, a finite element approach based on the Hertzian contact law and Sun's higher-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 changes due to transverse impact at the center are calculated
