The Laser adhesion test developed for testing bond strength of a coating on its substrate requires a good knowledge of shock wave propagation in such media. Experiments carried out on plasma sprayed copper samples, about 14% porous, with velocity interferometer system for any reflector measurements display the discrepancy of previously used models. Hence, a one-dimensional formulation of the compaction process, based on a simple P-α model, is proposed to improve the correlation between experimental and computed data signals obtained on a plasma sprayed copper under dynamic loading. Besides, this improvement allows the estimation of the bond strength of a plasma sprayed copper on aluminum substrate. %G English %L hal-00275593 %U https://hal.science/hal-00275593 %~ UNIV-BREST %~ INSTITUT-TELECOM %~ ENSMP %~ ENSTA-BRETAGNE %~ UGA %~ CNRS %~ UNIV-GRENOBLE1 %~ UNIV-POITIERS %~ INPG %~ SIMAP %~ ENSMP_MAT %~ PARISTECH %~ ENSTA-BRETAGNE-LBMS %~ ENIB %~ INC-CNRS %~ PSL %~ ENSMP_DEP_MM %~ ENSMP_DR %~ ENSMP-PSL %~ TEST2-HALCNRS
