Abstract. Very often, in nature as in technique, the process of liquid flow takes place inside a highly compressible porous layer (HCPL). In these processes, the elastic forces of the solid phase of the porous layer are negligible in comparison with the hydrodynamic forces. Such processes were named in 2001 ex-poro-hydrodynamic (XPHD). Recently, a study of the impact process in XPHD conditions was performed, for circular and rectangular aligned plates. The impact of a rigid sphere on a HPCL, in XPHD conditions, is analyzed in the present paper.
