Ferrites are soft magnetic materials that have a wide range of uses in microwave circuits. Many otherwise flight-qualified parts may have a variety of defects arising from fabrication and handling. A finite-element analysis (FEA) was performed to design a simple proof test for a particular planar ferrite core geometry. A 3-point bend test and three different geometries of 4-point bend tests were modeled to determine the distribution of tensile stress ...
