This proposal aims to explore a novel optical approach for full-field strain measurement and design verification of load-resisting members such as landing gear components. This new technique, referred to as shearography, is equivalent to a full-field strain gage permitting measurement of strain distribution over a large area. The technique does not require installing gages, and it is fast, precise and non-contacting. unlike holographic interferometry, shearography does not require special vibration isolation, and therefore it is applicable in a field/production environment. The proposed investigation will focus on a feasibility study.
