Software for Economic Optimal Control Modelsn a pulse travels in a test specimen with sound attenuation the spectrum and the center frequency of the pulse is changed with the traveled sound path. But even the bandwidth-dependent DGS diagram is calculated for a fixed center frequency. A method to derive and to consider the frequency-dependent

State of the Art: DAC and DGS,bed. How to derive a special DGS diagram for a certain probe from the general DGS diagram is explained as well as the necessary adaptations for sound attenuation and other influences. Examples for sizing using the DGS method is given for a straight beam probe and for an angle beam probe.

The New Probe Technology, Single Element Probes, Necessary adaptations are taken into account. The new angle beam probes generate rotationally symmetric sound fields as expected. The DGS accuracy in the working range defined in the EN ISO 16811:2011 is significantly better than the accuracy achieved with traditional angle beam probes.

New Probe Technology, Phased Array Probes,ngle of the phased array probe. Not only the delay laws are determined but for each angle all other data needed are determined in this chapter. With this data a special DGS diagram can be derived from the general one for each angle making it easy to use the DGS method for sizing with phased array angle beam probes.

Convert SDH into FBH and Vice Versa,er. The term equivalent diameters is used when both holes are generating the same amplitude at the given sound path. This method can be applied vice versa calculating a side-drilled hole from a given flat-bottomed hole.
