A comparison of intensities of singular stress field for bonded cylinder under tension and bending
Full text linkIn this paper, the stress field at the interface corner edge of a bonded cylinder under bending is discussed by comparing with that under tension. Asymptotic description of the stress field under the bending consists of the singular stress term and the non-singular stress term as well as that under the tension. The similarity relation between the singular stresses under the tension and the bending is confirmed by performing 3D FE analyses on the bonded cylinders under the tension and the bending which are subdivided by the same mesh pattern. The ratios of the intensity of the singular stress field under the bending to that under the tension are computed changing material combinations variously, the maximum and minimum values of the ratios are shown in the table and the chart according to Dundurs' parameter (α,β). The intensity of singular stress field for the bonded cylinder cannot be controlled by Dundurs' parameter uniquely. However, because the differences between the maximum and minimum values are small, the ratios can be controlled by Dundurs' parameter. Then, the ratios are larger than 0.7 and smaller than 1.0 in almost all material combinations with α(α-2β) < 0

IInfluence of Strain Rate for Notch- Bend strength on ductile Cast Iron
Full text linkProceedings of 5th International Conference on Fracture Fatigue and Wear, FFW 2016, 24-26 August 2016, Kitakyushu, JapanIn this study, the notch-bend strength (σb,max) which is useful to structural design was considered for High Si Solid Solution Strengthened Ferritic Ductile Cast Iron. Then, the application of the high Si ductile cast iron to wide industrial fields was discussed at room temperature. Dynamic three-point bending tests were conducted on Charpy V-notch specimens in the range of stroke speed, 10-3~102 mm/s, at 22°C. Even though the absorbed energy of fracture process was in the lower shelf region, the notch-bend strength (b,max) did not
decrease with increasing the strain rate. These results indicate b,max is insensitive to the strain rate. Therefore, the authors think that the high Si ductile cast iron has wide industrial application potentiality at room temperature
Effect of the Junction Capacitance by Open Circuit Voltage Decay Method : Construction of the Model Including Current Component
Full text link電力技術／電力系統技術／半導体電力変換技術合同研究会, 3月8日-9日, 2016年,
九州工業大学 戸畑キャンパス, 福岡県 We discussed applying the open circuit voltage decay (OCVD) method to measure carrier lifetime of power devices. A deviation of the carrier lifetime was confirmed by TCAD simulation on low level injection conditions. Introducing a transition model of carrier, a high accuracy measurement could be achieved

PCB base novel ultra-small current sensor: design tool and application
Full text link半導体電力変換／モータドライブ合同研究会, 1月22日-23日, 2016年, 立命館大学 びわこ・くさつキャンパス（ＢＫＣ）, 滋賀県 Ultra-small sensor with print-circuit-board (PCB) technology has been developed. The current sensor has been realized high accuracy with smaller size than commercialized Rogowski coils. We developed an in-house special high speed design tool on MATLAB so that we can design arbitrary shape sensor for IGBT module current monitoring
