1. Simulations of experimental crack development in ceramic material with notched specimen
Master-uppsats, KTH/HållfasthetsläraSammanfattning : Low-density armour often uses ceramic materials, as their high compressive strength and relatively low weight make the material ideal for moving in the field. The ballistic protection works by redirecting the plastic flow of the projectile radially, which reduces penetration. LÄS MER
2. Comparing different methods of measuring particle size for pharmaceutical excipients
Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)Sammanfattning : In pharmaceutical science, particle size is one of the most fundamental parameters of materials, but different particle-sizing analysis methods lack a uniform standard for measuring irregular particle size, making it difficult to compare the accuracy and applicability of different particle-sizing analysis methods. Experiments on excipients used in pharmaceuticals are carried out in this paper by laser diffraction analysis (Malvern wet and dry), dynamic image analysis (Qicpic), and microscopic methods (Qicpic, SEM, and light microscopy) to determine the applicability and limitations of each method, as well as to clarify their advantages and disadvantages.

3. FE-Modelling of a Joint for Cross-Laminated Timber
Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknikSammanfattning : Woodbe Engineering AB is a freshly started company that has developed a new type of joint for cross-laminated timber (CLT). The joint does not include any metallic fasteners, which improves sustainability, the ergonomics for the workers and time efficiency. LÄS MER
4. Reinforcement Layout in Concrete Pile Foundations : A study based on non - linear finite element analysis
Master-uppsats, KTH/BetongbyggnadSammanfattning : The main topic of this thesis concerns the behavior of concrete pile cap supported by four piles with two varying positions of longitudinal reinforcements. The positions include top of piles and bottom of the pile cap. For this purpose, non-linear finite element models of a pile cap are created using software ATENA 3D. LÄS MER
5. Adhesive modelling in multi-material structures : Evaluating the strength and fatigue life of adhesive joints
Master-uppsats, Linköpings universitet/Mekanik och hållfasthetsläraSammanfattning : Advancements in material science and manufacturing techniques are enabling the use of lightweight metal alloys and polymer composites in several combinations and shapes for producing more efficient and lightweight structures for automotive applications without compromising strength, stiffness and/or durability. When evaluating the strength of the structure, the joints are of importance. LÄS MER
