- Abstract
- Models for transmitting and receiving probes to be used with the mass-spring lattice model are presented in this work. The transmitting probe is modeled via a distribution of traction along the specimen boundary. The validity and versatility of the model is demonstrated by various examples of transmitting probes. The output voltage of a receiving probe is modeled as proportional to the net normal force acting on the probe face as a result of arriving waves from the interior of the specimen. Simulation for a simple example case shows that the model can produce an output voltage signal that has a waveform similar to the typical output signal in real ultrasonic tests and that the wedge model works well. Incorporation of the probe models developed here into the mass-spring lattice model is expected to provide a useful tool for the simulation of actual ultrasonic testing.
