Numerical Analysis and Theoretical Verification on the Dynamic Response of Typical Components under Explosion Load

To analyze the response of float glass under explosion load, the model was developed by the method of FEM simulation combined with stress theory. The numerical simulation results show that the stress caused by the blast wave on the center of the glass panel is continuous, while the stress around the glass is instantaneous. The displacement on both sides of the glass is larger than that at the center and at the four corners of the glass. The effective stress at the center of the glass is 86.08 MPa by numerical simulation. However, the effective stress at the center of the glass is 87.75 MPa by theoretical calculation. The error rate between the simulation result and the theoretical result is only 1.90%. Therefore, it is proved that the theoretical expressions in this paper are reliable for calculating the effective stress of single float glass under explosion load.
