Comparison table for methods discussed.

The method usedAdvantagesDisadvantages

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
