Elastic wave propogation on the plate

Please login with a confirmed email address before reporting spam

A cylindrical block with dimensions of 10 mm in height, 10 mm in radius, and 1 mm in bottom layer is placed on top of the rectangle block (200x200x5 mm) in order to observe elastic wave propagation. Next, I apply a body load (sin(2*pi*1e3*t)) to the center of the rectangular block. The material for the layer is (user defined as matching material between the aluminum plate and the cylindrical PZT transducer, with cp of 3400 m/s, cs of 1920 m/s, and density of 2280 kg/m^3). The rectangular block is aluminum plate, and the cylindrical block is PZT 5H. I also want to see the voltage waveform across the transducer.How to proceed can you guide me
