“…ℎ is the integration constant) with the left hand side representing the normalised kinetic energy per mass of the system. If ϵ is positive, the force-displacement gradient increases and the system represents hardening [19], in which case the plane plot encompasses an elliptic manifold, as is the case here (as illustrated in Fig. 3), while in the circumstances of negative ϵ the softening of the stiffness would occur.…”

“…While the transient deformation at the first approximation was concurrent with that of numerical models, prediction of the response was limited to the loading phase only. Feldgun et al [19] developed an SDOF model for rectangular plates with various boundary conditions subjected to a uniformly distributed exponential pulse load. Static and dynamic analyses were conducted and results compared with those from the numerical models as well as the available experimental tests.…”

“…ey are a series of the asymptotic curves inscribed in the vertical and horizontal asymptotes. To nd the points on the curves, either we use analytical methods [21,22] or numerical methods [23] and sometimes FEM analysis [24]. In the x-y plane, the vertical axis displays F max /K e y el , whereas horizontal axis displays x I/y el K e M e , I is the impulse, and F max is the maximum explosion forces.…”

“…It is much easier than the classical method of the pressure-impulse diagram and FEM analysis. As shown in [21][22][23][24], and also in this paper, the high-delity analytical or FEM models cannot predict explosion response without knowledge about explosion overpressure and pulse duration. e inaccuracy of the P-I diagram in the asymptotic region is clearly shown in this paper via Tables 1 and 2.…”

“…Response of rectangular thin plates, undergoing large deflections during explosion, was investigated in work [15]. However, the results obtained cannot be used for constructing EVP, based on cellular polycarbonate, capable of exiting locks, because the authors studies plates with fixed, clamped edges.…”
