On the laboratory scale NDT methods are a valuable tool to determine target characteristics in terms of the elastic properties (wave velocity) before, during, and after hypervelocity impact experiments.
3) AE techniques enable further determination of the exact point of impact in hypervelocity impact experiments.
2013), Deformation of dry and wet sandstone targets during hypervelocity impact experiments, as revealed from MEMIN program.
Much of the design information about hypervelocity impact comes from so-called hydrocodes.
The PHD project is designed to photograph hypervelocity impact events in order to accumulate statistical data about how fragments behave.
These tests have included much smaller impact energies at and below the threshold of damage, different impact materials, and hypervelocity impact conditions designed to simulate micrometeoroid and orbital debris damage.
Also, since it is desirable to have the impact sensing system not only detect ascent debris impacts, but also those of micrometeoroid and orbital debris (MMOD) during orbit, testing has been performed to measure sensor response to hypervelocity impacts.
The capacity for measuring hypervelocity impacts
in a controlled environment allows Sandia scientists to measure relevant material properties to calibrate codes such as CTH.
components for satellites) has to be designed to sustain extreme temperatures, which may vary hundred degrees in short periods of time, and extreme mechanical loadings like hypervelocity impacts
