1. Micro-CT based finite element models for mechanical strength assessment of glass ceramic scaffolds obtained through the robocasting technique
University essay from KTH/HållfasthetsläraAbstract : In this thesis, micro computed tomography (μ−CT) scans of a bio-glass scaffold produced by the robocasting technique was used to create finite element method (FEM) models with the purpose of determining its mechanical strength. Prior to this, a Matlab script was used to create several simplified geometries of the scaffold in an effort to determine the importance of scaffold design parameters (such as the fiber compenetration between two adjacent printing planes) on the strength of the scaffold.

2. The Investigation of Crack Propagation in Cortical Bone using a Phase Field Fracture Approach
University essay from Lunds universitet/Avdelningen för Biomedicinsk teknikAbstract : Human cortical bone tissue is a complex and strong composite material, with the ability to resist damage via slowing, stopping or redirecting propagating cracks. However, the ability is impaired with age. At the microscale, changes are seen both in terms of increased porosity and as changes in local material parameters. READ MORE

3. Assessment of creep damage in Fe-Ni-Cr alloys
University essay from KTH/Hållfasthetslära (Avd.)Abstract : It is only a matter of time before components working in high temperature environments fail due to creep. Design for creep is therefore of vital importance to maximize the lifetime of components and reduce costs that may arise from maintenance and replacement of components. READ MORE

4. Application of Dynamic Grouting to Improve the Grout Spread Using Varying Aperture Long Slot (VALS) : AN EXPERIMENTAL STUDY
University essay from KTH/Jord- och bergmekanik; KTH/ByggvetenskapAbstract : In the past centuries, grouting has been one of the most common techniques in geotechnical engineering to strengthen and seal underground structures. Concerning increasing demands for tightness and cost efficiency, cement-based grout has been one the most frequent used materials. READ MORE

5. Olinjärt ultraljud för undersökning av sprickor i skelettet hos häst, en pilotstudie
University essay from SLU/Dept. of Clinical SciencesAbstract : Fissurer och odislocerade frakturer hos häst kan ibland vara svåra att upptäcka utan avancerad bilddiagnostik. Det är dock viktigt att diagnostisera dem i tid för att hindra att skadorna förvärras. READ MORE
