Fatigue Crack Propagation Behavior and Life Prediction of Welded Joints of SMA490BW Steel for Bogies
نویسندگان
چکیده
In this paper, the precrack propagation behavior of an SMA490BW welded joint in core zone and heat-affected was analyzed through experiments based on FRANC 3D ABAQUS cosimulation method, life prediction these cracks also investigated. The results show that experimental crack path rate weld agree well with simulation results, a small relative error. span prefabricated higher than zone. Furthermore, regarding for two samples, error obtained using about 5%, which verified method their accurate feasibility.

Fatigue Life Prediction for Welded Joints with Known Initial Crack
The inspection of various structures often detects a fatigue cracks developed during long service life. These fatigue cracks significantly reduce remaining fatigue life and fatigue strength. Influence of the initial fatigue cracks size in non-load-carrying fillet-welded one-sided transverse attachment joints on the remaining fatigue life and fatigue strength is considered in this paper. A compu...
متن کاملFatigue Life Assessment of Welded Joints Considering Crack Propagation Based on Hot Spot Stress
In this study, fatigue test and crack propagation analysis of welded joints in ships and offshore structures were performed. The test models have two types of welded joints, T-joint and double plate. Test data is presented in S-N curves obtained by the Hot Spot Stress (HSS) approach. The S-N data for each length of crack were appraised to define the fatigue life of crack initiation and propagat...
متن کاملFatigue Life of Repaired Welded Tubular Joints
In this study, the effect of repair on fatigue life of tubular joints is investigated. Six cracked specimens precedently subjected to fatigue loading undergone to weld repair. Two of those specimens were shot peened before primary fatigue loading. It is shown that repair gives rise to about 150% increase in fatigue life for original specimens while the increase of fatigue life for shot-peened ...
متن کاملFatigue Life Prediction of Rivet Joints
Strength reduction in structures like an aircraft could be resulted as cyclic loads over a period of time and is an important factor for structural life prediction. Service loads are emphasized at the regions of stress concentration, mostly at the connection of components. The initial flaw prompting the service life was expected by using the Equivalent Initial Flaw Size (EIFS) which has been re...
متن کاملFatigue Crack Detection and Sizing in Welded Steel Structures
The paper gives an outline of the non-destructive evaluation (NDE) methods currently being pursued at the Admiralty Marine Technology Establishment, Dunfermline, Scotland. The methods are being used to locate and characterise fatigue cracks in high yield strength welded steel structures. The techniques have been applied principally to large fatigue models (5' and 9' diameter) as part of a compr...
