ASSESSMENT OF CRACKED PIPES BEHAVIOR BY FRACTURE MECHANICS CRITERIA
The paper presents the methods used to assess the behaviour of cracked pipes subjected to internal pressure by applying the Linear Elastic Fracture Mechanics criteria (LEFM). It is also described an analysis of a cracked steam pipe used in Romanian power plants.
Keywords: fracture mechanics, pipe, fracture toughness, heat resistant steel
Cuvinte cheie: mecanica ruperii, conducte, tenacitate la rupere, oţel termorezistent
