  1. 1. Metamodelling of a Finite Element Analysis of a Drilling Process with Replaceable Inserts

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Samy Akrouh Ettaghadouini; [2019]
    Keywords : drilling; speed; feed; CAD; FEM; simulations; metamodel; neural network; optimization;

    Abstract : The aim of this project is to create a metamodel from a drilling tool with replaceable inserts from FEA of the machining process using MATLAB and ABAQUS. This report contains research in drilling and in metamodeling using neural networks and the work from the design of the CAD, through FEA and simulations, to the metamodeling, excluding the optimization.

  3. 3. Implementation and validation of an isogeometric hierarchic shell formulation

    University essay from KTH/Bro- och stålbyggnad

    Author : Michael Loibl; [2019]
    Keywords : Isogeometric Analysis; Shell; Locking; Kirchho-Love; Reissner-Mindlin; Three-Dimensional Shell I;

    Abstract : Within this thesis, thin walled shell structures are discussed with modern element formulationsin the context of the Isogeometric Analysis (IGA). IGA was designed to achieve a directinterface from CAD to analysis. According to the concept of IGA, Non-Uniform RationalB-Splines (NURBS) are used as shape functions in the design and the analysis.

  4. 4. CAE modelling of cast aluminium in automotive structures

    University essay from Linköpings universitet/Mekanik och hållfasthetslära; Linköpings universitet/Mekanik och hållfasthetslära

    Author : Subrat Singh; Sreehari Veditherakal Shreedhara; [2019]
    Keywords : Material failure model; LS- Dyna; Non-linear Finite Element analysis; Cast aluminium; Explicit FEA; LS-DYNA; Drop tower; Spring tower; Strut Tower; FEM; CrachFEM; ANSA;

    Abstract : In the automobile industry, there is a big push for the automotive car manufacturers to base engineering decisions on the results of Computer Aided Engineering (CAE) solutions, and to transform the prototyping and testing, from a costly iterative process to a final verification and validation step. The variability in components material properties and environmental conditions together with the lack of knowledge about the underlying physics of complex systems often make it impractical to make reliable predictions based on only deterministic CAE models.

  5. 5. 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
