Application of digital phase-shift shadow Moiré to micro deformation measurements of curved surfaces
Publikováno v:
ResearcherID
The shortcomings of conventional shadow Moire topography have in the past been improved by means of the phase-shift method which enhances the sensitivity and allows to process the fringe patterns automatically. This paper presents a digital implement

Plastic pipes dominated the low pressure gas distribution piping market during the last decade. Research on steel pipes has long since indicated that the susceptibility to rapid crack propagation (RCP) increases with increasing diameter. Although mos
