The device for the local repair or strengthening of an elongate body exhibiting a change in its integrity, by winding one or more layers of tape around the elongate body, comprises two half rings, each having two ends configured to come into contact with one another, means for moving the two half rings relative to one another until they surround the elongate body, without touching, and means for translating the two half rings relative to one another along an axis perpendicular to the axis of the elongate body until the ends of the half rings are in contact to form a ring surrounding the elongate body. In the embodiments, the device includes, on at least one of the half rings, at least one centering pin corresponding, in the other half ring, to an opening with a shape complementary to the shape of the centering pin.

Device for processing an elongate body

A method for determining a mechanical performance parameter of a structure in which damage has caused a wall of the structure to change from an initial shape to a damaged shape. The method comprising for geometrically characterizing an external surface of the damaged shape; modeling a test body comprising a surface substantially identical to the external surface of the damaged shape; modeling a test wall having a portion of a shape substantially identical to the initial shape; calculating a deformed test wall and a stress state related to the deformation, the deformation of the test wall being caused by a relative displacement of the test body and the test wall, the relative displacement being configured to give the deformed test wall an external surface substantially identical to the external surface of the damaged shape; and evaluating mechanical performance of the deformed test wall.

Method of determining mechanical performance of a structure

A device () and a method for locally repairing or reinforcing an elongate body (), said device () being intended for winding one or a plurality of layers of pre-impregnated polymerizable strip around the elongate body (), said device () comprising: &#x2014;releasable means () of attachment around the elongate body (), &#x2014;means for the rotational movement of support structure () around the means () of attachment, &#x2014;means for the longitudinal movement of a spool () of a pre-impregnated polymerizable strip relative to the support structure (), said support () comprising means for limiting the movement of the spool to a predetermined path, said spool () being unwindable when it is subjected to a given tension, &#x2014;means for bringing the spool () into rotational and translational movement around the elongate body (), causing the pre-impregnated polymerizable strip to be wound around said body.
