1. Isogeometric analysis as a tool for large deformation shape optimization
University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/HållfasthetsläraAbstract : The framework for isogeometric analysis (IGA) is presented, especially the construction and use of non-uniform rational B-splines (NURBS) to represent geometry, and a method utilizing IGA for structural optimization both for linear elastic and non-linear elastic deformations is implemented. Topology optimization of a linear elastic cantilever is performed, showing that IGA is inecient for topology optimization. READ MORE

2. A Matrix-less Method for Approximating the Eigenvectors of Toeplitz-like Matrices
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : Matrix-less methods (MLM) have successfully been used to efficiently approximate the eigenvalues of certain classes of structured matrices. Specifically, the method has been used to approximate the eigenvalues of Toeplitz and Toeplitz-like matrices. READ MORE

3. Implementation and validation of an isogeometric hierarchic shell formulation
University essay from KTH/Bro- och stålbyggnadAbstract : 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. Numerical Methods for the PDES on Curves and Surfaces
University essay from Institutionen för datavetenskapAbstract : Curves and surfaces are manifolds that can be represented using implicit and parametric methods. With a representation in hand, one can define a partial differential equation on the manifold using differential tangential calculus. READ MORE
