26. Simulation of Stainless Steel Tube Extrusion
Sammanfattning : The simulation of hot extrusion processes is a difficult and challenging problem in process modeling. This is due to very large deformations, high strain rates and large temperature changes during the process. LÄS MER
27. Modeling and experimental characterization of large biaxial strains and induced anisotropy in pearlitic rail steel
Sammanfattning : Large shear strains accumulate in the near-surface region under the running band of railway rails. In this region, rolling contact fatigue cracks often initiate, causing major problems for the railway industry. LÄS MER
28. Elastic Press and Die Deformations in Sheet Metal Forming Simulations
Sammanfattning : Never before has the car industry been as challenging, interesting, and demanding as it is today. New and advanced techniques are being continuously introduced, which has led to increasing competition in an almost ever-expanding car market. LÄS MER
29. Towards Virtual Tryout and Digital Twins : Enhanced Modeling of Elastic Dies, Sheet Materials, and Friction in Sheet Metal Forming
Sammanfattning : Competition and complexity in the global car market are continuously increasing. To gain an edge in the market while making a profit, each competitor in the market needs a strong focus on technology development. Such a focus will increase the value of the product for the customers. LÄS MER
30. Numerical models for degradation of concrete in hydraulic structures due to long-term contact with water
Sammanfattning : The durability of concrete is of major concern in all types of concrete structures where the combined effect of exposure conditions and the type and quality of the concrete material usually determines the rate of degradation. Furthermore, there are synergy effects between different deterioration mechanisms, which means that the combined rate of degradation is higher than the sum of the individual rates of each mechanism.
