1. Influence from temperature variations in stacking fault energy on the mechanical properties of stainless steels
University essay from KTH/MaterialvetenskapAbstract : This paper investigates the mechanical properties and deformation mechanisms of austenitic stainless steels and how they relate to the material property of stacking fault energy (SFE) and its relation to temperature and nickel content. Austenitic stainless steels are commonly used and well known for good mechanical properties and deformation characteristics. READ MORE

2. Experimental Testing of EPS-foam
University essay from KTH/HållfasthetsläraAbstract : The aim of this master thesis was to investigate the mechanical properties of ExpandedPolystyrene (EPS) through experimental testing. The strain was measured on thespecimen’s surface with Digital Image Correlation (DIC), in order to investigate howthe first principal strain at fracture initiation depends on the loading of the material.

3. Numerical Modelling of Combined Forming and Punching of Sheet Metal for Heat Exchanger Applications
University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaperAbstract : In this work a strategy for numerical simulation of punching during concurrent pressing of stainless steel sheet metal has been investigated accounting for the stress triaxiality and Lode angle parameter. Modelling of the damage evolution of a sheet metal is a useful tool within the field of engineering and materials science, and can provide useful information regarding material capabilities in a design process.

4. Effect of Proton Irradiation on the Mechanical Properties of Fe-10Cr-4Al in Liquid Lead
University essay from KTH/FysikAbstract : Among the structural materials under consideration for future lead-cooled fastreactors, special attention is paid to ferritic Fe-10Cr-4Al due to its superior corrosionand erosion protective properties, as well as its insensitivity to liquid metalembrittlement in liquid lead. This thesis gives an inside look into the radiation damageproperties of the alloy and the possible embrittlement scenarios. READ MORE

5. Pre-Straining Operation : Prediction of Strain Paths Within a Forming Limit Diagram
University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknikAbstract : In a Sheet Metal Forming (SMF) operation, complex geometries in multi-stage forming processes are mostly common. Forming a blank, major and minor straining willoccur. Follow the straining of the blank elements over the forming process will provide its strain paths. READ MORE
