Accuracy of a domain decomposition method for the recovering ofdiscontinuous heat sources in metal sheet
نویسنده
چکیده
This paper describes a method for the retrieval of discontinuous heat sources involved in a metal cutting process. Two smoothing techniques were used in the present study in order to smooth noisy sensor data recorded by temperature sensors. The two smoothing techniques are a least squares polynomial t and a La-grangian smoothing. These data are then used to recover the heat source. It is found that the least squares polynomial provides over-smoothed results and the Lagrangian smoothing produces phyically acceptable results of the retrieved heat source. ? The last two authors are partially supported by the EP-SRC Grant GR/L98862.

متن کاملOutput-only Modal Analysis of a Beam Via Frequency Domain Decomposition Method Using Noisy Data
The output data from a structure is the building block for output-only modal analysis. The structure response in the output data, however, is usually contaminated with noise. Naturally, the success of output-only methods in determining the modal parameters of a structure depends on noise level. In this paper, the possibility and accuracy of identifying the modal parameters of a simply supported...
