ational method G2 is not based on filtering of the Navier-Stokes (NS) equations, and thus no Reynolds (subgrid) stresses are introduced. Instead the mathematical basis is ϵ-weak solutions to the NS equations and weak uniqueness of such ϵ-weak solutions. Based on this mathematical framework we constr

Introductionion of solids can be studied from different viewpoints and their classification is by no means universal Loosely speaking, two general categories emerge from the vast content of plasticity. One is the phenomenological approach within the framework of continuum mechanics, with particular emphasis on

Introduction to Material Structures atoms or molecules, to the higher structure of metals, alloys, plastics, ceramics and rocks, and to the even larger structure such as machine or geological features which are built from these materials. While useful knowledge of material behaviour will only be gained at the right scale of observati

Meso-Damage Theoryrch frontiers in the failure theories of materials. The scope of nowadays damage mechanics theory encompasses researches originated from macroscopic, meso and microscopic levels, with . playing a central role along the interface between solid mechanics and material sciences. The development of meso-

Prediction of Formabilityuires varying amount of stretching and drawing, to which bending and buckling are added. Traditionally, prediction of forming behaviour of materials are based on tensile test data, simulative tests and continuum mathematical models in which major input material variables are average macroscopic prop

Grain Boundary Engineering and Related Topics boundaries, The first one concerns with the microscopic effect of grain boundaries on the dislocations during plastic deformation, and the second one deals with the macroscopic effect of boundaries on the bulk mechanical properties. In the early stages of deformation, the grain boundary regions are

Introduction to Material Structuresported by Adcock in 1922 in a copper-nickel alloy, almost twelve years before the birth of the dislocation theory of crystals which tried to understand the atomic process involved in slip in crystals. Shear banding was thought to be so complicated by that time that further research interests on t
