1. Finite Element Macro-modeling of a Historical Masonry Building : Influence of Isotropic vs Anisotropic Plastic Material Model Assumption in Static Analysis
University essay from KTH/Bro- och stålbyggnadAbstract : In this study, a macro-modeling strategy is implemented in a bearing wall with arch openings in an existing historical masonry building. This is to investigate what differences and similarities can be observed from the assumption of an orthotropic versus an isotropic constitutive material model. READ MORE

2. Continuum damage modeling of delamination in paperboard
University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/HållfasthetsläraAbstract : This work concerns the creasing and folding of a continuum paperboard material model developed by Eric Borgqvist. Creasing is an operation that induces permanent deformation in the material, undertaken for the folding to be performed along a straight fold line without any in-plane cracks. READ MORE

3. Failure Modeling of Curved Composite Beams : Numerical Modeling of Failure Onset and Propagation in L-Profile Beams
University essay from KTH/LättkonstruktionerAbstract : The high strength/stiffness-to-weight ratio that composite materials exhibit has led to the utilization of composites as alternative to traditional materials in weight-critical applications. However, the highly anisotropic nature of composites renders the strength prediction under complex loading challenging. READ MORE

4. Simulation of Delamination Migration in Laminated Composite Structures - An Approach Combining Extended Finite Elements and a Cohesive Zone Model
University essay from Lunds universitet/HållfasthetsläraAbstract : Fiber-reinforced polymer matrix composites are being used increasingly in lightweight applications where high strength and stiffness is required. One of the main challenges with designing components from such materials is to predict the ultimate strength and behaviour of the structure. READ MORE

5. Anisotropic material modeling and impact simulation of a brush cutter casing made of a short fiber reinforced plastic
University essay from Linköpings universitet/Hållfasthetslära; Linköpings universitet/Tekniska högskolanAbstract : A popular way to reduce weight in industrial products without compromising the strength or stiffness is to replace components made of metal by plastics that have been reinforced by glass fibers. When fibers are introduced in a plastic, the resulting composite usually becomes anisotropic, which makes it much more complex to work with in simulation software. READ MORE
