1. Simulation of bending and hydroforming : constitutive modeling and failure prediction
Sammanfattning : In recent years, the automotive industry has shown increased interest in reducing weight and improving environmental effects of cars. This has lead to an increased use of lightweight parts. LÄS MER
2. Constitutive modeling of friction materials
Sammanfattning : [abstract missing].... LÄS MER
3. Modeling of foams for impact simulations
Sammanfattning : Stimulated by the strong drive in the automotive industry to reduce energy consumption,and, linked to that, the need to reduce weight, this thesis concerns modeling of foams forimpact simulations. To start with, a continuum hyperelasto-viscoplastic model is developedwithin the framework of Theory of Porous Media. LÄS MER
4. A Study on Sandwich Structures : Development, Mechanical Characterization and Numerical Modeling
Sammanfattning : Legislative demands force the automotive industry to reduce greenhouse gas (GHG) emissions. At the same time, crashworthiness must not be compromised. A ve-hicle’s GHG emissions, such as carbon dioxide, is dependent on its fuel consump-tion. Lowering the vehicle weight, reducing fuel consumption, will therefor reduce emissions. LÄS MER
5. On mechanical characterization and multi-scale modeling of Lithium-ion batteries
Sammanfattning : Over the last few decades, rechargeable lithium-ion batteries have been extensively used in portable instruments due to their high energy density and low self-discharge rate. Recently, lithium-ion batteries have emerged as the most promising candidate for electric vehicles and stationary energy storage. LÄS MER
