1. Closed-die forging and slab hot rolling with focus on material yield : some industrial problems analysed by FEM
Sammanfattning : The thesis is focussed on improving the material yield in closed-die forging and rolling. The former is restricted to the manufacturing of heavy crown wheels and front axle beams and the latter to the hot rolling of steel slabs. To enhance the yield the commercial FE-codes Form2D and Dyna3D are used. LÄS MER
2. Methods for material parameter estimation : global and local approach
Sammanfattning : The rapid development of computing technology has made powerful tools, such as finite element codes, available for more and more companies. The use of simulation tools, predictive engineering, is a prerequisite today in product development. LÄS MER
3. Mechanism-based flow stress model for Ti-6Al-4V : applicable for simulation of additive manufacturing and machining
Sammanfattning : Ti-6Al-4V has remarkable properties such as high specific mechanical properties (viz. stiffness, strength, toughness, fatigue resistance), corrosion resistance, biocompatibility etc. These properties make it attractive for applications in aerospace, chemical industry, energy production, surgical implants, etc. LÄS MER
4. Extended impregnation kraft cooking of softwood : Effects on reject, yield, pulping uniformity, and physical properties
Sammanfattning : Converting wood into paper is a complex process involving many different stages, one of which is pulping. Pulping involves liberating the wood fibres from each other, which can be done either chemically or mechanically. LÄS MER
5. Mesoporous material systems for catalysis and drug delivery
Sammanfattning : Hybrid material systems possess multi-functional properties which make them intriguing for the materials science community since very early dates. However, it is not straightforward to produce such material systems. A smart and efficient approach is necessary to extract the desired properties of each component under the desired conditions.
