Dynamic loading on a yacht mast

The exam­p­le shows an appli­ca­ti­on of NDT on a 30m CFK yacht mast (lower left). The time avera­ge result of the SE1 mea­su­re­ment and dyna­mic loa­ding by our Pie­zo­s­ha­ker (lower right) is indi­ca­ting a lar­ger deli­mi­ta­ti­on below the sur­face start­ing from a small visi­ble crack. Usual­ly, small cracks are often seen on the sur­face, but not all are rela­ted to del­a­mi­na­ti­on, which needs any repair.
