  1. 16. Simulating Residual Stress in Machining; from Post Process Measurement to Pre-Process Predictions

    Master-uppsats, KTH/Industriell produktion

    Författare :Joanne Proudian; [2012]
    Nyckelord :;

    Sammanfattning : Metal cutting is a widely used manufacturing technique in the industry and has been the focus of many research and studies in both academic and industrial fields. Prediction of induced residual stresses in a machined component is essential in a component’s fatigue life and surface integrity approximation. LÄS MER

  3. 17. Residual stresses in sandwich components

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Joan Pascual; [2012]
    Nyckelord :;

    Sammanfattning : High residual stresses are likely to develop in honeycomb sandwichparts after autoclave co-curing and can lead to manufacturing defects.By using finite element unit cell models, these stresses have been calculatedfor standard panels and for panels where different core blocksare joined with adhesive.

  4. 18. Finite element analysis of thermally induced residual stresses in functionally graded materials.

    Master-uppsats, KTH/Materialvetenskap

    Författare :Arash Hosseinzadeh Delandar; [2012]
    Nyckelord :FEM; FGM; residual thermal stresses; crack; failure; sintering;

    Sammanfattning : Functionally graded materials (FGMs) are advanced materials and their main characteristic is microstructure and composition variation over the volume of the specimen. This variation of the composition results in changing of material properties in the component. LÄS MER

  5. 19. FINITE ELEMENT MODELING TO VERIFY RESIDUAL STRESS IN ORTHOGONAL MACHINING

    Magister-uppsats, Blekinge Tekniska Högskola/Avdelningen för maskinteknik

    Författare :CHANDRA SHEKHAR PRASAD; [2009]
    Nyckelord :FEM; ALE; ABAQUS;

    Sammanfattning : The aim of this thesis paper, to create a numerical model to examine the residual stresses induced by orthogonal machining in the finished work piece and the model is validated by comparing with experimental result. The finite element method is used to simulate and analyze the residual stresses induced by a orthogonal metal cutting process. LÄS MER

  7. 20. Simulation of Residual Stresses in Castings

    Kandidat-uppsats, JTH, Maskinteknik

    Författare :Ruben Lora; Jayesh Namjoshi; [2008]
    Nyckelord :Residual stresses • Thermo-mechanical • Quasi-static • Castings • FEM • FDM • Numerical simulation • Solidification • Thermal analysis • Stress analysis • Meshing • Abaqus • Magmasoft • Hypermesh • Matlab • ProEngineer;

    Sammanfattning : This work presents a study and implementation of the simulation of residual stresses in castings. The objects of study are a cast iron truck Hub part (provided by the company Volvo 3P) and an optimized version of the Hub resulting from the application of a topology optimization process. LÄS MER
