1. Evaluation of a computational method for natural fiber-reinforced plastics
University essay from KTH/HållfasthetsläraAbstract : The importance of using natural fiber composites (NFCs) has been addressed as a substitution for synthetic fibers, such as glass and carbon fibers. This substitution contributes significantly to reducing greenhouse gas emissions, aligning with the environmental responsibilities of engineering industries. READ MORE

2. Validation of Finite Element Model of a Tetra Pak Package
University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknikAbstract : There is a high dependency on accurate finite element models in the packaging industry for concept selection, design and virtual validation of packages. One of themost used materials for these packages is High-Density Polyethylene (HDPE). Thismaterial is highly anisotropic, strain rate dependent and has different behavior intension and compression.

3. Size effect in wood : Characterization of mechanical properties using digital image correlation method
University essay from Uppsala universitet/Tillämpad mekanikAbstract : As a natural composite material, wood exhibits complex structural char-acteristics and diverse behavior under compression and tensile forces. Itsanisotropic nature results in mechanical properties that vary depending onthe load direction along its longitudinal, tangential, and radial grains. READ MORE

4. Multi-Scale Topology Optimization of Lattice Structures Using Machine Learning
University essay from Uppsala universitet/Tillämpad mekanikAbstract : This thesis explores using multi-scale topology optimization (TO) by utilizing inverse homogenization to automate the adjustment of each unit-cell's geometry and placement in a lattice structure within a pressure vessel (the design domain) to achieve desired structural properties. The aim is to find the optimal material distribution within the design domain as well as desired material properties at each discretized element and use machine learning (ML) to map microstructures with corresponding prescribed effective properties.

5. 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
