Two Examples of Spatially Resolved Shock-Wave Tests
As a rule, kinematic parameters of shock-wave loads are monitored at one point of a sample or are averaged over a transducer cross section. However, there is a set of problems for which it is important to obtain a spatial picture of the phenomenon. In these cases, spatially resolving instrumentation promises to make an essential contribution. The recently developed line-imaging interferometer technique (Baumung et al., 1996b) provides a capability for simultaneously recording the velocity history at many points along a line on the sample surface. In this chapter we present examples of the application of this capability to the study of spall fracture and of adhesion phenomena.
