Comparison table for methods discussed.
| The method used | Advantages | Disadvantages |
| TNO + SDOF simulation | (1) Reliable source for checking FEM (deflection) (2) Simple compared to FEM | (1) Low fidelity compared to FEM analysis (2) Includes the model for history of overpressure |
| Pressure-impulse curves | (1) Simple to find the ductility and displacement | (1) Inaccuracy in asymptotic region (2) Needs overpressure history (3) Low fidelity compared to FEM analysis |
| Empirical formulas (17) and (20) in this paper | (1) No need for history of overpressure (2) Simple to find the ductility and displacement (3) Reliable source for checking FEM (deflection) | (1) Low fidelity compared to FEM analysis |
| FEM analysis via ABAQUS | (1) High fidelity of the model (2) Availability of results in any location (3) Local buckling details | (1) Needs overpressure history (2) Meshing difficulties and model complexity (3) Verification of the results by another method |
