  2. 11. Mechanical Modelling of Powder Compaction : Due to Corona is not possible to attend this defense in person, instead attend via this link: https://play.kth.se/media/t/0_mbkr2jhi​

    Author : Hjalmar Staf; Per-Lennart Larsson; Göran Frenning; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Cutting tool inserts, for instance used in steel machining, have the requirement to be toughand are therefore most often manufactured out of cemented carbides, using powdermetallurgy. Manufacturing components with powder metallurgy has its advantages in highproductivity and good net shape. READ MORE

  4. 12. Alternatives for Finite Element Analysis of Blade Forging

    Author : Behzad Soltani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; residual stresses; blade forging; flow approach; metal forming; quasistatic implicit; dynamic explicit; forging; solid approach; finite element method; closed die forging;

    Abstract : This thesis is a theoretical and numerical study of the weaknesses and capabilities of alternative finite element procedures for simulation of the blade forging problem and also an analysis of the practical aspects of that process. An overview is presented of the finite element method for non-linear problems with elastoplastic constitutive relations, focusing on quasistatic implicit and dynamic explicit approaches. READ MORE

  5. 13. Study of Pumping Pressure and Stop Criteria in Grouting of Rock Fractures

    Author : Jalaleddin Yaghoobi Rafi; Håkan Stille; Mikael Rinne; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock Mechanics; Grouting; Solid Mechanics; Hållfasthetslära;

    Abstract : Today practice of grouting is based on empirical approaches in that, pumping pressure and stop criteria are determined by benchmarking similar projects. Considering a maximum limit for grouting pressure would allow applying a relatively high pressure that may lead to jacking of the fracture or even uplift of the rock mass. READ MORE

  6. 14. Phase-field modeling of surface-energy driven processes

    Author : Klara Asp Grönhagen; John Ågren; Suzana Fries; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase-field method; surface energy; solute drag; solid-state sintering; multicomponent multiphase flow; wetting; liquid-phase sintering; spinodal decomposition; CALPHAD; Materials science; Teknisk materialvetenskap;

    Abstract : Surface energy plays a major role in many phenomena that are important in technological and industrial processes, for example in wetting, grain growth and sintering. In this thesis, such surface-energy driven processes are studied by means of the phase-field method. READ MORE

  7. 15. Robust intersection of hexahedral meshes and triangle meshes with applications in finite volume methods

    Author : Frida Svelander; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; triangle-hex intersection; overlapping triangles; degenerate mesh; volume fraction; area fraction; cut cell; conjugated heat transfer.; triangle-hex intersection;

    Abstract : The topic of this thesis is the intersection of a structured hexahedral grid and one or more triangle meshes. The interest in the problem has arisen in connection with a finite volume method for simulation of conjugated heat transfer. READ MORE
