Figure 9
The ENGIN-X virtual laboratory. Three-dimensional models of the laboratory and sample are used for planning of experiments, in this case to measure the axial (a) and radial (c) directions of the strain tensor of the 190 kg pipe shown in (b). The three-dimensional model of the sample is produced either from simple primitive objects, such as in (a) and (c), or from detailed descriptions of the actual surface of the specimen (d) using the ENGIN-X coordinate-measuring machine. The precise alignment of the sample in the laboratory (both real and virtual) is achieved using two theodolites. |
