Abstract: When there is a failure on the external sheath of a flexible pipe, a high value of hydrostatic pressure is transferred to its internal plastic layer and consequently to its interlocked carcass, ...

Abstract: When submitted to high external pressure, flexible pipes may collapse. If the external sheath is damaged, all the external pressure is directly applied on the internal polymeric layer that transmits the loading to the ...

Abstract: This work presents a derivation of equivalent loads, coming from the integration of hydrostatic pressure fields on the internal and external walls of a curved pipe, which is modeled as a Euler-Bernoulli beam. To achieve ...

Abstract: An oblong ring-type structure is composed by two straight segments (length L) and two semicircular segments (radius R). It can be used to generate traveling waves, being applied to build linear piezoelectric motors and ...

Abstract: When the external sheath of flexible pipes experiences damage, seawater floods the annulus. Then, the external pressure is applied directly on the internal polymeric layer, and the load is transferred to the interlocked ...
