ABSTRACT: Two cylindrical vessels under internal pressure are used for this work in
order to study the influence of the position and size of defects on their
elastic and elastoplastic behavior. One contains two external longitudinal
semi-elliptic defects of different dimensions realized diametrically opposed.
The other contains the same defects but is circumferential. These defects are
carried out by elect-erosion. Strain gauges are placed in the neighborhood of
the defects of which the purpose is to obtain the strain distribution. This
work also allows the comparison between two defects of different dimensions,
which are of the same shape or different shapes. These defects are longitudinal
and circumferential semi-elliptical. The position of these defects relative to
the inner radius of a cylindrical pressure vessel is considered. The
deformations results are discussed.
