摘要：

In this paper three recently developed traction vector techniques will be experimentally validated. Common ground for the techniques are based on a modal expansion of the displacement field and utilization of sets of normal eigenmodes and displacement measurements in order to yield detailed descriptions of the traction vector field acting at the boundary. Comparison between the methods is made regarding the experimental estimation of traction vectors both point-wise and in an L-2-norm over the boundary in question. The results are good especially regarding the normed results. (C) 2004 Elsevier Ltd. All rights reserved.
