Method and device for determining a pressure load of a sample caused by a shock wave

摘要

The invention relates to a method for determining a pressure load of a sample (114) caused by a shock wave. In this case, a sample surface of the sample (114) is irradiated with a laser beam (104) through a transparent cover layer (116) and an absorption layer (118) arranged between the sample surface and the cover layer (116) in order to ablate material of the absorption layer (118). to generate a plasma (204) by which the sample (114) is exposed to the shock wave (202). Subsequently, a plastic deformation of the sample surface caused by the shock wave is detected to obtain at least one deformation parameter (122). Finally, the deformation parameter (122) is evaluated using at least one laser parameter characterizing the laser beam (104) in order to determine the pressure load.
