The article is focused on the development of a methodology for the magnetic microwire finite element model creation, which have a bright prospect in terms of monitoring the mechanical stress inside the composite materials. The finite element model is based on a real geometry of a particular magnetic microwire. The glass coating of the magnetic microwire was mechanically removed and the information about the geometry was obtained by the microscope. Based on the photos the 3D model was created and the mesh of the magnetic microwire and the finite element model with boundary conditions were developed. The most important part of the article deals with the modelling of the magnetic microwire contact surfaces and the development of their finite element mesh. Once the finite element model is done, all properties for the static stress analysis are applied. In this context, the static stress analysis is performed and the results from the ANSYS APDL are presented. The article summarizes the new approach in investigation of magnetic microwire mechanical properties. The proposed finite element model can be also used for further investigation of magnetic microwires.
