  1. 11. Fatigue analysis of welded joints in a forestry machine : Utilizing the notch stress concept

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT); Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Martin Nyström; Tainan Pantano Tomaz; [2015]
    Keywords : Weld; Fatigue; Finite Element Method; Hot-Spot Method; Notch Stress Method; Structural Dynamics; Forestry Crane; Svets; Utmattningslivslängd; Finita-elementmetoden; Hot-spot; Notch-stress; Notch-spänning; Strukturdynamik; Skogsmaskinskran;

    Abstract : Welding is one of the most applied technics in the world for joining steel. Welds are liable to the phenomenon of fatigue, which is, primarily, the formation of a crack and consequently reduction of strength due to the action of time varying loads. Fatigue is one of the main causes of failure in steel structures. READ MORE

  3. 12. Accuracy Study in Predicting Fatigue Life for a Welding Joint.

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Emma Fredriksson; [2015]
    Keywords : ;

    Abstract : This thesis describes a comparative study between two calculations methods for life estimates of a welding joint. The two studied methods are the Effective Notch and Linear Elastic Fracture Mechanics (LEFM). The effective notch method is today used at GKN and gives an equitable accuracy relative the work effort for the method. READ MORE

  4. 13. Fatigue life analysis of weld ends : Comparison between testing and FEM-calculations

    University essay from Linköpings universitet/Hållfasthetslära; Linköpings universitet/Tekniska högskolan

    Author : Andréas Göransson; [2014]
    Keywords : Weld end; Fatigue; Fatigue Life; Calculation methods; Modelling; FEM; Comparison; Testing; LCF; Svetsslut; Utmattning; Beräkningsmetoder; Provning; Modellering; FEM; Jämförelse;

    Abstract : The thesis examines the fatigue life of weld ends, where very little usable research previously has been conducted, and often the weld ends are the critical parts of the weld. It is essential knowing the fatigue life of welds to be able to use them most efficiently. READ MORE

  5. 14. Effect of material grade on fatigue strength and residual stresses in high strength steel welds

    University essay from KTH/Lättkonstruktioner

    Author : Wasim Asgher; [2012]
    Keywords : Fatigue Strength; Fillet Welded Joints; Effective Notch Method; Residual Stress Simulation.;

    Abstract : This thesis work is concerned with effect of material grade on fatigue strength of welded joints. Fatigue strength evaluation of welded joints in as welded and post weld treated condition was carried out with effective notch method. Results of peak stress method have also been compared with those of effective notch method for as welded joints. READ MORE

  6. 15. Design Method for Strut-Beam Connection in Hinged Frames

    University essay from Lunds universitet/Byggnadsmekanik

    Author : Juan Cardenal; [2012]
    Keywords : ABAQUS; LEFM; failure modes; three-pin portal frames; shear stress; built-up haunches; framed joint; glulam; size effects; Technology and Engineering;

    Abstract : Glulam is almost exclusively the chosen material of timber frame structures. Of those, three-hinged (three-pin) portal frames are incomparably the most common type. Being both statically determinate and stable against horizontal forces in its own plane offer both practical (basic constructive details) and economical benefits. READ MORE
