Determining all Displacements, Strains and Stresses Full-Field from Measured Values of a Single Displacement Component

摘要

The ability to determine the individual components of displacement, strain and stress from measured values of a single component of displacement is demonstrated. Advantages of the method include its ability to significantly simplify the experimental technique by measuring only a single displacement component, to provide reliable results both full-field and at the edge of geometric discontinuities, and the lack of need to differentiate the recorded data physically. Results agree with those from thermoelastic stress analysis, strain gages and finite element analysis.
