The monolithic glass, without damage, under impact loading, is studied by the use of the coded finite element program. To predict the impact energy of monolithic glass like annealed glass and tempered glass, a finite element approach based on Sun's higher-order beam finite element and impact energy equation is proposed. For this purpose, the contact force-displacements, energy-displacement histories and velocity-acceleration histories etc. are calculated during all impact processes. And, also, by the calculations of the coded FEM program, the geometric parameter like thickness is investigated to determine their impact energy prediction of monolithic glass.
