چکیده
The structural materials used for LMFBR are austeniticsteels from Type AISI 304, 316 or steels which are simi-lar. Investigations show that a leak-be fore-break conceptcan be established for LMFBR piping systems and components,due to the ductile behavior of these steels and the opera-ting conditions. A major element of this concept is theknowledge of fatigue crack growth patterns. The experi-ments which were carried out show that initial flaws willonly grow slowly during the lifetime. The investigationsshould be extended into the plastic range. A test facili-ty is under construction, were components like nozzles,elbows and bellows can be tested under operational con-ditions with specified flaws in stress concentration areas.

An Infrared Interferometer for Elastoplastic Crack-Tip Field Investigation of Homogeneous and Bimaterial Beams: A Study of Three-Dimensional Effects and J-Dominance
An infrared interferometer capable of performing real-time full-field noncontacting deformation field measurements on optically rough surfaces is proposed as a tool for elastoplastic fracture mechanics investigations. The choice of the infrared wavelength allows interferometric measurements' on fracture samples with little or no surface preparation and is more tolerant of the damage accumulatio...
متن کاملA continuum damage failure model for hydraulic fracturing of porous rocks
A continuum damage mechanics (CDM) based constitutive model has been developed to describe elastic, plastic and damage behavior of porous rocks. The pressure sensitive inelastic deformation of porous rocks together with their damage mechanisms are studied for drained and undrained conditions. Fracture mechanics of microcrack andmicro-void nucleation and their coalescence are incorporated into t...
متن کاملUnified Constitutive Equations to Describe Elastoplastic and Damage Behavior of an X100 Linepipe Steel
The deformation and fracture of the high strength steel which is used to fabricate grade X100 steel pipe were investigated at room temperature, on plate and pipe. Anisotropic behaviour was characterized by using tensile tests conducted along different directions. The fracture toughness of plate and pipe materials are compared using compact tension (CT) and Charpy V-notched tests. In both cases,...
متن کاملFracture mechanics-based life prediction of a riveted lap joint
In this paper, three-dimensional modeling of the fatigue crack growth profiles was performed in a simple riveted lap joint. Simulation results showed that mode I was dominated on the one side of the plates and the crack straightly grew on this side, while the other side of the plates was in a mixed-mode condition and the crack propagation path was not straight on this side. Afterward, the fract...
متن کاملModeling and Simulation of Spherical and Cylindrical Contact Theories for Using in the Biological Nanoparticles Manipulation
The low Young's modulus of biological particles results in their large deformation against the AFM probe forces; therefore, it is necessary to study the contact mechanics of bioparticles in order to predict their mechanical behaviors. This paper specifically deals with the contact mechanics of DNA nanoparticles with spherical and cylindrical shapes during manipulation. In previous studies, ...
