Summary: By using shock induced by impact of thin metallic foils laser accelerated onto a substrate covered by a coating, it is possible to produce localised tractions inside the target. An analytical and numerical study of this process evidence the optimized conditions in order to generated first the traction at the interface of generic targets, realizing a debonding test.
