3次元DEMによる合わせガラスの衝撃貫通破壊解析

抄録

It is important to know the impact fracture behaviors in the safety design of the laminated glass plate. However, the three-dimension analysis for the impact fracture behaviors of the laminated glass plate is not done over the current. In this research, the impact penetration fracture when the impact body collides with the center of the laminated glass plate is analyzed by PFC3D. It is the general three-dimensional program that uses the Distinct Element Method (DEM). DEM is suitable for the analysis of the fracture behavior of the non-individual body and the break-up body. The analytical results are compared with the experimental one and the validity of analytical results are checked. By this research, it is obvious that the penetration speed and the loss energy increase as the impact velocity, radius and mass of the impact body increase. Moreover, the relations between the parameters of impact body and fracture behavior are clarified.
