In the work presented in this paper, a sensitivity analysis using the Morris screening method was carried out for a model of the Flooding Experiment with Blocked Arrays (FEBA) separate-effect test facility. The sensitivity analysis was conducted in the con ...
Bonded particle modelling (BPM) is nowadays being extensively used for simulating brittle material failure. In BPM, material is modelled as a dense assemblage of particles (grains) connected together by contacts (cement). This sort of modelling seriously d ...
Reinforced concrete being the most applied construction material today performs very well in most applications but still lacks durability under severe environmental conditions. Especially existing structures built decades ago show degradation. Using Ultra- ...
Smart structures with tunable damping and stiffness characteristics are of high interest to aerospace applications, but often require an external power source to be activated. This can be avoided by using highly concentrated silica suspensions, which exhib ...

The present work deals with the determination of mechanical properties of materials using instrumented indentation techniques. The main advantage of indentation testing is that it is relatively simple to perform and does not need any special and time-consu ...
Oxide dispersion strengthened (ODS) steels are being investigated as possible structural material for components of future nuclear power plants. The dispersoids in the matrix (yttria particles) serve as pinning points for moving dislocations, and thereby i ...
From conception to realization, Microrobotics: Methods and Applications covers all aspects of miniaturized systems that physically interact and manipulate objects at the microscale. It provides a solid understanding of this multidisciplinary field, which c ...
Ingots of an oxide dispersion strengthened reduced activation ferritic steel with the Fe-14Cr-2W-0.3Ti-0.3Y(2)O(3) chemical composition (in wt.%) were synthesized by mechanical alloying of elemental powders with 0.3 wt.% Y2O3 particles in a planetary ball ...
An analysis of the tribo-mechanical properties of the Ni-Co system, at the submicrometric contact scale, is conducted using displacement sensing nanoindentation. In particular, the influence of contact depth and surface finishing methods on the hardness, H ...
A statistical model for fracture of aligned-whisker-reinforced metals was used to interpret tensile data of a TiB-reinforced titanium alloy. From this analysis, a TiB whisker strength of 8.0 GPa with a Weibull modulus of 2 was predicted. The analysis is co ...
