Non-destructive testing
Shearography
Non-destructive inspection of composites, honeycomb panels, bonded structures, and thin-walled metallic components under controlled loading.
Method, equipment and applications →Optical methods for technical diagnostics
Start with the measurement objective
Select a method for non-destructive testing, residual-stress determination, or full-field displacement and strain measurement. Each method page then connects the principle, equipment, software, and applications.
