Multi-Field problems

    C3M is experienced in the development of engineering solutions that take into account interdependencies between different physical fields. This includes strong and weak coupling of mechanical, thermal and magnetic fields.

    An example of multi-field approach developed by C3M is simultaneous analysis of inductive heating and radial forging. The electromagnetic field, produced by coil carrying the alternating current, induces eddy currents in the electrically conducting material, which passes trough the coil. As a result of induced eddy currents the material heats resistively. The phenomenon is also known as inductive heating where the thermal response is coupled with the magnetic behaviour. Further couplings between thermal and mechanical effects are due to temperature dependent material response, heat generation from plastic work and friction as well as heat loses through deformation dependent die contact areas and to the environment. Final shape, surface quality, micro-structural changes and densification of forged product therefore strongly depend on the degree to which temperature field achieved during the inductive heating is harmonised with forming operation.
