  1. 1. Probabilistic non-linear finite element analysis of concrete buttress dams

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Adrian Ulfberg; [2019]
    Keywords : ATENA; FREET; SARA; probabilistic; numerical; Kalhovd; FEA; FEM;

    Abstract : Assessment of concrete buttress dams today consists of using analytical methods to investigate the stability in different failure modes. However, they simplify the problem at hand and neglect certain important features linked to geometry and thus not truthfully appraise the structures real stability. READ MORE

  2. 2. Industrial Sheet Metal Forming Simulation with Elastic Dies

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik; Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Markus Lind; Viktor Sjöblom; [2018]
    Keywords : Elastic Stamping Dies; FEA; LS-Dyna; Sheet Metal Forming; Structural Analysis;

    Abstract : As part of the development process for new stamping dies, in the automotive sheet metal forming (SMF) industry, the majority of all forming operations are simulated with the Finite Element Method (FEM) before the dies are manufactured. Today, these simulations are conducted with rigid tools under the assumption that there are no tool deformations.

  3. 3. Implementation of inverse motion form finding in commercial software

    University essay from Lunds universitet/Hållfasthetslära

    Author : Sean Mooney; [2018]
    Keywords : Inverse motion; finite element method; FEM; FEA; Technology and Engineering;

    Abstract : This Masters' dissertation investigates the possibility of implementing the concept of inverse motion form finding in a commercial software. The inverse motion approach finds the initial, undeformed geometry of a design such that it obtains its desired design shape when service loads are exerted on the design. READ MORE

  4. 4. A micro-CT investigation of density changes in pressboard due to compression

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Johan Stjärnesund; [2018]
    Keywords : Micro computed tomography; μCT; pressboard; density; densification;

    Abstract : Pressboard, a high-density cellulose-based product, is used both as load bearing structures and dielectric insulation in oil-filled power transformers. During transformer operation, mechanical forces and vibrations are applied on the material. READ MORE

  5. 5. Concept study for cost and weight reduction of a barge container sized module

    University essay from KTH/Lättkonstruktioner

    Author : Ricky Andersson; [2018]
    Keywords : sandwich panel; structural optimization; cost reduction; weight reduction; high-strength steel; finite element analysis.;

    Abstract : The intention of this thesis is to develop, evaluate new concepts and look over the current design for a container sized barge module. By request of Group Ocean, a cost and weight reduction is the main improvement criteria along with keeping the strength of the module. READ MORE
