6.5 kV n-Channel 4H-SiC IGBT with Low Switching Loss Achieved by Extremely Thin Drift Layer
See details
(Switzerland: Trans Tech Publications, 2016), 9 page(s)
Thin drift layers were used to realize n-channel 4H-SiC IGBTs with an extremely low switching loss. The thickness of a drift layer was 60 µm, which was designed for a blocking voltage of 6.5 kV. An on-voltage of 5.4 V was obtained at a collector current of 100 A/cm2 and the specific differential on-resistance at...

3D Numerical Model of the Subsoil-Structure Interaction and Comparison of the Results with Experimentally Measured Values
See details
(Switzerland: Trans Tech Publications, 2017), 13 page(s)
The influence of the physically-nonlinear behaviour of the structure and interaction between the upper structure and foundation are the aspects which influence the results of the subsoil-structure interaction analysis. The experimental measurement of stress and strain and monitoring of stress-strain relations by i...

3D Topography Analysis of Ball-End Milled H-13 Die Steel Surfaces Using Wavelet Decomposition Method
See details
(Switzerland: Trans Tech Publications, 2016), 10 page(s)
Optical profiler is employed to measure the surface topography of H-13 die steel machined by ball end cutter. By using 2D discret wavelet decomposition, the topographies of different frequency bands are obtained and the influence of cutter posture on varying frequncy bands topography is studied. The results show t...

Accuracy and Material Properties in Incremental Forming for a Multi-Step Expanding Approach
See details
(Switzerland: Trans Tech Publications, 2015), 10 page(s)
In incremental sheet forming the material properties change dependent on the wall angle. In addition to sheet thinning, material hardening can be observed and for stainless steel the formation of strain induced martensite has been reported. These process characteristics have been extensively examined for the formi...

Accurate and Traceable Calibration of the Stiffness of Various AFM Cantilevers
See details
(Switzerland: Trans Tech Publications, 2015), 10 page(s)
Atomic force microscope (AFM) is widely used to measure nanoforce in the analysis of nanomechanical and biomechanical properties. As the critical factor in the nanoforce measurement, the stiffness of the AFM cantilever must be determined properly. In this paper, an accurate and SI-traceable calibration method is p...

Achieving Concrete Durability in Chloride Exposures
See details
(Switzerland: Trans Tech Publications, 2016), 9 page(s)
Obtaining durability in concrete structures over a long service life in chloride exposures requires knowledge of the concrete properties, relevant transport processes, depths of cover as well as minimization of cracking and construction defects. For example, imperfect curing can result in depth-dependent effects o...
