Existence of cracks in industrial structures is one of the important causes of their failure, especially when they are subjected to important axial compressive forces that might lead to buckling. Therefore, it must be considered in stress analysis and designing and loading of such structures. In this paper, the buckling and post-buckling behaviors of stainless-steel cracked plates under axial c...

We have used ceramic capillary tips generally used in the microelectronics industry for the production of DNA microarrays. The ceramic tips improve the morphology of microarray elements, allow higher element density, and increase printing tip life over the customary slotted stainless-steel pins. Ceramic tips are less expensive than steel pins and allow printing from 1536-well sample source plat...

We have constructed a sliding block cryotribometer designed to measure friction at cryogenic temperatures and UHV conditions. An optical cryostat and high speed video was used to monitor the motion of the block. The temperature range of the measurements was 4–460 K. Both the static and dynamic friction coefficients were determined for a steel ball on stainless steel, sapphire, and PTFE (Teflon)...

Quasi-static and dynamic damage mechanisms in alumina tiles were investigated. The tiles were under a variety of boundary conditions at the tile's edges during impact NATO 0.3 cal. AP rounds with hardened and sharpened steel core were used. The alumina tile samples were 50x50 mm2 area, the thicknesses ranging from 5 to 12 mm. 'he tiles were mounted in a special confinement frame, which enabled ...

B. Grizelj, J. Cumin, Mechanical engineering Faculty in Slavonski Brod, Slavonski Brod, Croatia D. Grizelj, Siemens, Zagreb, Croatia. This paper deals with the eff ects of technological parameters used in the V-die bending process, on the obtained product properties and dimensions. By variation of the tool geometry, several cases of steel sheet bending process are observed through the FEM simul...
