ABSTRACT:
Pipes undergoing torsion stresses at one fixed extremity, the other extremity being flexibly supported, and in particular, exhaust pipes for motor vehicles. The concentration of stresses at the fixed end are eliminated and distributed in the center of the pipe by reinforcing its moment of inertia and its rigidity at the fixed extremity, and by creating a series of localized zones with a reduced moment of inertia in the center area, where the stresses undergone by the pipe at its fixed end are distributed in limited fashion. The invention is especially applicable to the exhaust pipes of internal combustion engines.
