“…If the difference between the calculated velocity and its value at the previous iteration is greater than the given tolerance, the corresponding coordinates, strains and stresses of the shell, as well as of the contact pressures (48) and (49), are calculated using the current velocity value. This allows one to calculate the new values of the nodal forces using Equation (38) and to progress on to the next iteration.…”

SUMMARYThe paper presents a coupled 2D Godunov-variational difference approach for soil-structure interaction due to a nearby explosion. Owing to the high-intensity dynamic loads, complex processes take place, including transient separation of the buried structure from the surrounding soil, large deformations of the buried structure including loss of stability, and so on. The approach takes into account the irreversible bulk compaction of the soil medium and is based on the relationships of the shock and rarefaction waves with finite-difference equations of the shell motion, using a simple iteration method. The model reduces the contact problem to the self-similar symmetric Riemann problem.The proposed approach is demonstrated by the solution of a buried explosion in the proximity of a lined tunnel buried in soil. The peak contact pressure envelope along the lining was studied. It was found that for an explosion in the proximity of a relatively rigid shell, the maximum value of this envelope is located at some distance from the lining's axis of symmetry.

SUMMARY The Riemann problem for an irreversibly compressible three‐phase medium has been solved. This solution introduces the maximum medium density that is attained in the process of active loading. The possible wave configurations have been analyzed, and the corresponding equations for the evaluation of the contact pressure and velocity have been obtained. The existence and uniqueness of the solution has been proven. The technique of the Riemann problem's solution for the arbitrary Lagrange–Euler mesh was developed. Examples of the Riemann problem solution for various wave configurations show that neglecting the bulk elastic plastic deformations yields significant errors in the results both quantitatively and qualitatively. The effect of the air volumetric content in a three‐phase soil medium on the Riemann problem solution has been investigated. Copyright © 2013 John Wiley & Sons, Ltd.
