Optimal Sensor Placement for Inverse Finite Element Reconstruction of Three-Dimensional Frame Deformation

Table 3

Comparisons among deformations computed from iFEM and deformations extracted from ANSYS. Computed results contained system errors, combining errors of sensor-locations with errors of strain-measurements. Displacements expressed in mm.
