Single sheet tester having open magnetic path for measurement of magnetostriction of electrical steel sheet

Comparative Harmonic Loss Measurement of Grain Oriented and Non-oriented Magnetic Sheets Using a High Precision Single Sheet Tester

 Abstract: Local flux may be distorted in many regions of core, although total flux is usually sinusoidal. When attempting to predict the loss distribution in materials operating under localized distorted flux conditions, which occur in machines and transformer cores, it is essential that proper account of the waveform be taken. Moreover for development of new magnetic materials and generation ...

Low-Carbon Steel Sheet Asymmetric Single-Point Incremental Forming: Analysis and Optimization of the Surface Roughness (TECHNICAL NOTE)

Surface roughness (SR) has an adverse effect on the appearance of low-carbon steel parts, formed in the asymmetric incremental sheet forming (AISF) process, particularly those requiring painting operation. The purpose of this study is to investigate the effects of AISF process parameters on the surface roughness of an asymmetric part formed on low-carbon steel sheets. The parameters are feed ra...

Failure characteristics of a dual-phase steel sheet

Failure in ductile sheet metal structures is usually caused by one, or a combination of, ductile tensile fractures, ductile shear fractures or localised instability. In this paper the failure characteristics of the high strength steel Docol 600DP are explored. The study includes both experimental and numerical sections. In the experimental sections, the fracture surface of the sheet subjected t...

Analysis of deformation-induced surface morphologies in steel sheet

The surfaces of strained mild steel sheet specimens were examined with scanning laser confocal microscopy. Rigorous assessments were employed to establish the form of the roughness data. The small deviations from the ideal conditions observed in these assessments indicated that the stochastic process responsible for surface roughening does not conform to stationary, Gaussian, Markov statistics....
