We report the synthesis of Methylammonium Lead Iodide (CH3NH3PbI3) nanowires by a low temperature solution processed crystallization using a simple slip-coating method. The anisotropic particle shape exhibits advantages over nanoparticles in terms of charg ...
Spandrel elements in unreinforced brick masonry buildings with timber floors consist of a masonry spandrel supported by either a timber lintel or a masonry arch. When subjected to seismic loading, the force-deformation relationship of such spandrel element ...
Solid state diffusion is a very complex mechanism and, up until recent studies, such properties had mainly been conducted by macroscopic methods that do not yield true material properties. This has been a major problem for materials development regarding e ...
This paper proposes a simple but powerful approach to determine the constitutive equation of tempered martensitic steels from micro-hardness tests. Finite element simulations were used to investigate the plastic flow in the contact region between the tip a ...
Existing bridges may have been designed and constructed according to codes without any provisions for seismic design and detailing. Particularly in countries with moderate seismicity, such as Switzerland, modern seismic design standards might have been int ...
Deformation mechanisms in nanocrystalline electrodeposited Ni (26 nm) and Ni-Fe (12 nm) are studied by strain rate sensitivity experiments and in situ mechanical testing during X-ray diffraction. We find a relatively low strength for Ni-Fe, which may be as ...
The influence of the carbon content on the microstructure, phase transformation and hardness of an iron-based cermet is studied. The cermet is constituted by a high-alloyed steel as matrix, and TiCN particles (50 vol.%) as reinforcement. The material is pr ...
This study presents a dynamic-induced direct-shear model to investigate the dynamic triggering of frictional slip on simulated granular gouges. An incident P-wave is generated as a shear load and a normal stress is constantly applied on the gouge layer. Th ...
We perform a hybrid experimental and numerical study of the localization of deformation in thin spherical elastic shells under indentation. Past a critical indentation, the deformation of the shell ceases to be axisymmetric and sharp points of localized cu ...
The mechanical behavior of partially solidified Al-Cu alloys is investigated to assess the influence of mushy zone deformation on hot tearing. For this purpose, the results of a semi-solid tensile test conducted in situ using X-ray microtomography are comp ...
