Repair of Internal and External Longitudinal Failures of Pipes by Fabric Composite Reinforcement

Abstract

The first part of the paper deals with the FEM computation of strains, stresses and deformations in the surrounding area of internal and external longitudinal artificial failures with a set of given geometrical dimensions in steel pipes. The aim of this analysis is to clarify the case in which the pipe fails. When a pipe fails and needs repair or reinforcement, this is called critical case. In the second part of the paper the repaired pipes are investigated. In this case the task is to determine the number of CFRP layers needed for repair. The critical cases and the question of repair
answered numerically.
