Chinesische Staatsunternehmen verstehen (or scanning the sample) holding θ = θ(critical), yield images of these flaws. The quality of these images is good and provides an excellent method of near surface flaw detection. However, certain quantitative aspects of the critical angle phenomenon remain unresolved, making detailed image interpr

Recently, for this latter case, a new acoustic line-focus beam‘ has been introduced with which the nonscanning reflection acoustic microscope can appropriately pick up acoustic properties of solid materials, including acoustic anisotropy..

Geschichte der TCM in China und im Westen not ductile, so that very good quality materials must be produced and a good knowledge of the harmfulness of the defects is required. This harmfulness will be deduced from a comparison of the actual dimensions of the defect to the critical length ac for that defect, corresponding to the fracture of the sample under a known stress field σ. .
