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

Area of Science:

• Materials Science
• Mechanical Engineering
• Structural Analysis

Background:

• Float glass is a common material used in structures, making its response to blast loads critical for safety.
• Understanding the stress and displacement dynamics of glass under explosion is essential for designing blast-resistant structures.

Purpose of the Study:

• To analyze the response of float glass under explosion load.
• To validate theoretical stress calculations against numerical simulations.

Main Methods:

• Finite Element Method (FEM) simulation was employed to model the glass response.
• Theoretical stress calculations were performed and compared with simulation data.

Main Results:

• Numerical simulations indicated continuous stress at the glass center and instantaneous stress at the edges.
• Glass displacement was greater at the sides compared to the center and corners.
• The effective stress at the center calculated via simulation was 86.08 MPa, versus 87.75 MPa theoretically, with a 1.90% error rate.

Conclusions:

• The theoretical expressions for calculating effective stress in single float glass under explosion load are reliable.
• FEM simulation combined with stress theory provides accurate predictions for blast load responses in glass panels.
