Bending Wave

The structural intensity technique is usually used to estimate vibration power flow in structures. This method is used to determine vibration power flow in thin naturally orthotropic plates. The bending wave is considered to find general vibration power transmission in the frequency domain that is not approximated by far field conditions. This intensity formulation defines power flow per unit width of the plates (W m−1) similar to that of the conventional idea. Power flow estimation is formulated using cross-spectra of field signals, facilitating the use of a fast Fourier transform analyzer.

The Subject

The mechanism of three-point thick plate bending finished via the specially designed experiment device in this paper. The deformation process discretization analysis completed via gridding method. T2 copper thick plate was chosen as the subject for the experiment, and the ratio of punch radius to sheet thickness was R/t = 1 and 2. The surface of the specimen was meshed by use of fine ink pen. The forming process was accomplished on the experimental facility of three-point free of sheet metal bending. And photos of the specimen in the forming process were recorded on every moment by use of digital camera. The grid pictures of specimen were gotten by image processing, and the accuracy is comparable with finite element analysis.  Compared with the grid pictures, the inside and outside of the thick plate bending angle wasn’t strict equaled in the forming process, and there was a trend that the angle would increase gradually from inside to outside. The angle difference would be decreased under the effect of the correction force after spring-back.
