Method suitable for effective testing of magnetoelastic effect in magnetic materials should fulfill the following requirements: • magnetic circuit of the tested sample should be closed. Open magnetic circuit causes demagnetization, which reduces magnetoelastic effect and complicates its analysis. • distribution of stresses should be uniform. Value and direction of stresses should be known. WebJul 14, 2004 · First, strains invalidate the magnetic calculation; in particular, the magnetostatic self‐energy is strain‐dependent. Second, magnetization invalidates the elastic calculation; the stresses (whose definition is somewhat arbitrary) need not be symmetric or even constitute a tensor. Third, small‐strain formulas, valid only to the first ...
