Unformatted text preview: A 5 mm thick semi-infinite steel plate is subject to a tangential field created by a coil, H = 2644.1 A/m at a frequency
of 50 Hz. The material conductivity, σ is 5 x 106 S/m. The B-H curve is defined by the equation B = H/(a+b |H|),
where a = 156, b = 0.59. η, a geometry constant, is given to be 10.016. Compute the eddy current loss. Figure 220.1 Thick Steel Plate Problem Sketch and Finite Element Model Material Properties

A nonlinear harmonic analysis is performed with PLANE53. The command macro POWERH is used to calculate
the power loss in the plate.
Verification was performed by comparing the ANSYS results to those obtained through the use of the univers...
