Tracer Crack [patched] Top - Cine

If you are tasked with locating and analyzing a crack top using cine tracer methods, follow this standard operating procedure (SOP):

Apply tensile, bending, or fatigue loading. The "cine tracer crack top" becomes visible as the crack opens and closes. The top edge will exhibit the widest displacement. cine tracer crack top

Remove coatings, rust, or scale from the suspected area. For tracer methods, the surface roughness should be below 125 µin (3.2 µm). If you are tasked with locating and analyzing
