Deflection measurements using moiré gap effect
- 49 Downloads
The moiré gap equation originally derived by Sciammarella and Chiang has been generalized to include linear and rotational mismatches. The equation is then applied to the measurement of deflection of beams and plates. The method has the advantages of being simple in comparison with other optical whole-field methods. The application of moiré gap effect to the study of dynamic problems is also discussed.
