Numerical studies of craters produced by explosions on or underneath the ground surface
are scarce An ability to predict the anticipated size of crater is crucial to identify the
corresponding damage that might be caused by a given explosive charge, or to assess the
magnitude of the charge if this was not known. In this paper, a non-linear dynamic...

... the parameters required to define the cap plasticity model are determined by a best match between the material properties obtained experimentally by Ambrosini et al., (2002) and those quoted in the ABAQUS Example Manual (2003). The soil properties and the corresponding cap plasticity parameters used are given in Table 1. ...Context 2
... it will be necessary to investigate variation of all the soil parameters before more generalized conclusions can be made. Therefore, Equation (12) can be used for prediction of the crater diameter in clay soils independent of density, but with properties otherwise as defined in Table 1 CONCLUSIONS This paper presents a fully coupled numerical analysis of air-soil-explosion interaction. The analysis procedures and the material models in the fully coupled analysis are validated by comparison with physical tests. ...Context 3

In the present world, the need for underground structures has grown many folds due to the increasing population, the advancement of public infrastructure, and the scarcity of land. Underground structures also provide attractive alternatives for storage of explosives and other military hardware. Being at shallow depth, their potential impact on the...
