000014488 520__ $$2eng$$aWe simulate flow phenomena that involve both fluids and elasto-plastic solids. The numerical model is the same for all materials and can handle high-speed flows, large deformations, frictionless contacts and plasticity. Hyperbolicity of the hyperelastic neohookean model is granted thanks to an explicit computation of the characteristic speeds. The plastic model satisfies a classic entropy inequality and we prove that it leads to a decrease in norm of the stress deviator tensor. Numerical illustrations of the method include air-helium, water-air shock interactions in three dimensions. A supersonic projectile-shield impact beyond the yield limit is presented.
