Static behavior of lattice structures produced via direct metal laser sintering technology
(Elsevier Ltd, 2017)The aim of this scientific work was the analysis of the micro lattice structures under uniaxial quasi-static compression loading with regard to the effect of unit cell size and strut diameter. A wide range of cubic lattice ... -
The effect of finely-divided fillers on the adhesion strengths of epoxy-based adhesives
(Elsevier Ltd, 2015)It was aimed to investigate the effect of five different fillers on the adhesion strength of the metal parts used in different industries by using T-peel and lap-shear tests with respect to ASTM D 1876 and ASTM D 1002 ... -
An elastic-plastic and residual stress analysis steel reinforced thermoplastic composite cantilever beam
(2010)In the present study an analytical elastic-plastic stress analysis is carried out for a low-density homogeneous polyethylene thermoplastic cantilever beam reinforced by steel fibers. The beam is loaded by a constant single ... -
The homogeneity map method for speckle reduction in diagnostic ultrasound images
(Elsevier B.V., 2015)This paper proposes a new method to reduce speckle noise in diagnostic ultrasound images by improving the speckle reduction capacity of an edge-sensitive filter. A homogeneity map is generated according to the local ... -
Microcontroller-based test system for determining the P-N type and Seebeck coefficient of the thermoelectric semiconductors
(Elsevier B.V., 2019)In this study, a microcontroller-based test system is designed and realized to determine the Seebeck coefficient (alpha) and electrical conductivity type of thermoelectric (TE) semiconductors. The test system uses Hot-Probe ... -
High temperature wear behavior of the surface-modified externally cooled rolls
(Elsevier B.V., 2018)Externally cooled rolls of a steel plant were coated using three different surface modification techniques, namely titanizing, boronizing and borotitanizing. The grown coatings were examined using optical microscopy, ... -
