1. 1. 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.

3. 2. A New H-Adaptive Method for Shell Elements in LS-Dyna

   University essay from Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Byggnadsmekanik

   Author : Ivan Oskarsson; [2006]
   Keywords : Technology and Engineering;

   Abstract : This thesis describes the development of a new h-adaptive method for shell elements in the explicit FE-code LS-DYNA. Adaptivity is used to obtain accurate results for large deformation analyses to a low computational effort. However, the present adaptive method available in LS-DYNA is based on a geometrical simplification. READ MORE
