The results of the simulations and the CONWEP calculation are shown in Figure 30.4.5.b.3.26. The absolute values of the maximum incident pressure agree well for the S6 mesh resolution, but the S10 simulation underestimates the results of the CONWEP calculation. For the S8 mesh resolution, the S8 and S10 simulations overestimate the CONWEP calculation. The S2 and S4 simulation results are less consistent with the CONWEP calculation. The S2 simulation underestimates the CONWEP calculation, while the S4 simulation overestimates the CONWEP calculation. For the S6 and S8 mesh resolutions, the two simulation results agree well with the CONWEP calculation. For the S10 mesh resolution, the S10 simulation overestimates the CONWEP calculation, while the S6 simulation underestimates the CONWEP calculation.
The current modeling results show that the CONWEP approach is a suitable technique to estimate the response of structures in the near-field and contact zone. However, it is necessary to expand the underlying physics of the CONWEP model to incorporate different explosive geometries. The future work will focus on the extension of the CONWEP model for other explosive shapes, including obtuse shapes. 827ec27edc
