Discontinuous boundary element method is applied to the solution of damage to structures. Finite volume method solves the pressure waves propagation in the air. Combination of both methods enables one a unique theoretical observation of the effect of explosion on solid structures in semi-enclosed media. Contact conditions among solid particles are discussed from both theoretical and application point of views. Two basic ideas of definitions of contact conditions are studied in details: soft contact - based on penalty formulation , and strong contact - starting by Uzawa's algorithm. Examples fr...
