__OTHER FORMATS__As well as peak property values

*Times of shock arrival, for a 2000 kg ANFO surface burst.*

If we use 'Interpolate at X for Y' to obtain the time at which the shock is at 100 metres, we get 192 milliseconds (as on previous page). Let's select Wave Profiles on the Data Format submenu and enter 192 in the dialogue box which appears. We get the following (assuming static overpressures is selected):

*Wave profile of static overpressure at time 192 ms. The
shock is at 100 m, travelling to the right (arrow added for illustration). The 'structure'
to its left at 77-78 m is a second shock.*

Next, we'll display the time history of static overpressure
at 100 m, by selecting __T__ime Histories on the Data Format submenu, entering 100 and
clicking OK:

*Time history of static overpressure at 100 m. The shock
arrives at 192 ms with peak overpressure 0.2056 atm. The second shock arrives about 60 ms
later. The Interpolate for Y at X option (Y=0) can be used to obtain the time of positive
overpressure duration, 45.93 ms, and the Integrate option used to obtain static
overpressure impulse, 3.95 atm-ms. Time histories like the one shown here are measured
using electronic pressure transducers.*

All of the graphical illustrations on this page can also be displayed numerically. Both graphical and numerical displays can be printed or saved to disk.
