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 ...
This work deals principally with two important issues and their interrelation: the evolution of damage in coated cemented carbide tools used for cold forming, and the assessment of mechanical behavior of cemented carbides under compressive contact loads. D ...
Tubular space trusses for bridge applications use thick-walled tubes. The reduction in fatigue resistance due to geometrical size effects is thus an important issue. In order to carry out a thorough study, both fatigue tests on large-scale specimens and ad ...
This paper gives insight into detail design of the MPU Heavy Lifter. The innovative structure is developed for offshore heavy lifting operations like removing or installing platforms. Its hull is composed of highly reinforced and prestressed lightweight co ...
Formulating effective coatings for use in nano- and biotechnology poses considerable technical challenges(1). If they are to provide abrasion resistance, coatings must be hard and adhere well to the underlying substrate(2). High hardness, however, comes at ...
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 ...
To improve the reduced available experimental data on the load capacity of full scale bridge deck slabs, 3 tests on a large scale bridge cantilever (10 x 4.2 m) were done. The cantilevers were tested under 4, 2 and 1 concentrated loads simulating traffic w ...
The scribe and break technique (or dicing) is a widely employed method in the industry of semiconductors to separate infrared laser diodes made from gallium arsenide (GaAs). The scribing step allows to create a precursor crack which is then propagated duri ...
We have developed hybrid AFM probes with SU-8 polymer body and full platinum and tungsten cantilever and tip. The fabrication process uses surface micromachining of a (100) silicon wafer. The metal (platinum or tungsten) is sputter deposited in oxidation s ...
Interface delamination during indentation of micron-scale ceramic coatings on metal substrates is modeled using discrete dislocation (DD) plasticity to elucidate the relationships between delamination, substrate plasticity, interface adhesion, elastic mism ...
