1. Toughness of Tool Steel
Sammanfattning : Toughness is the ability to resist tensile stresses in the presence of a notch or crack. Sometimes gross cracking of industrial tools, mould or dies, occurs due to insufficient toughness. As the economic consequences of the gross cracking are serious, the toughness of industrial tool material, generally tool steel, is of paramount importance. LÄS MER
2. Toughness enhancement in transition metal nitrides
Sammanfattning : Toughness enhancements can be induced in cubic-B1 transition metal nitride alloys by an increased occupation of the d-t2g metallic states. In this Licentiate Thesis I use density functional theory to investigate the mechanical properties of TiN and VN and of the ternaries obtained by replacing 50% of Ti and V atoms with M (M = V, Nb, Ta, Mo, and W) to form ordered structures with minimum number of inter-metallic bonds.

3. Modelling of fracture toughness using peridynamics : A Study of J-integral, essential work and homogenisation
Sammanfattning : Fracture toughness is one of the most important properties of a material. Being able toaccurately estimate the energy that goes into forming new crack surfaces is essential for the development of new materials, quality assurance, structural monitoring and failure analysis. LÄS MER
4. Fracture toughness properties of duplex stainless steels
Sammanfattning : Good toughness properties in base and weld material enable the use of duplex stainless steels (DSS) in critical applications. DSS offer high strength compared to common austenitic stainless steels. LÄS MER
