1. 1. Offset modeling of shell elements : A study in shell element modeling using Nastran

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : David Klarholm; [2016]
   Keywords : Offset shell elements; finite element; Nastran; shell element modeling; Rigid body connection; Rigid links; Kirchhoff shells; Multipoint constraint;

   Abstract : At Saab Aerostructures they are manufacturing a lot of parts for Airbus and Boeing. When these components are investigated using finite element analysis four-node Kirchhoff shell elements and a very fine mesh is often used. READ MORE

3. 2. Finite Element Modeling of Rubber Bushing for Crash Simulation - Experimental Tests and Validation

   University essay from Lunds universitet/Byggnadsmekanik

   Author : Oscar Jesus Centeno Gil; [2009]
   Keywords : Technology and Engineering;

   Abstract : Until recently, the general level of detail in full car crash models has not allowed a physical modeling of rubber bushings with solid elements. This is partly because of the difficulty in modeling the complex characteristic of rubber, but also due to limited understanding of the mechanical properties of rubber materials. READ MORE

4. 3. Prediction and Modelling of Fastener Flexibility Using FE

   University essay from Institutionen för ekonomisk och industriell utveckling

   Author : Freddie Gunbring; [2008]
   Keywords : finite element method; load distribution; flexibility; fastener; 3D FE; beam; connector;

   Abstract : This report investigates the feasibility and accuracy of determining fastener flexibility with 3D FE and representing fasteners in FE load distribution models with simple elements such as springs or beams. A detailed study of 3D models compared to experimental data is followed by a parametric study of different shell modelling techniques. READ MORE
