For an accurate description of electromagneto-thermomechanical systems, electromagnetic fields need to be described in a Eulerian frame, whereby the thermomechanics is solved in a Lagrangean frame. It is possible to map the Eulerian frame to the current placement of the matter and the Lagrangean frame to a reference placement. We present a rigorous and thermodynamically consistent derivation of governing equations for fully coupled electromagneto-thermomechanical systems properly handling finite deformations. A clear separation of the different frames is necessary. There are various attempts to formulate electromagnetism in the Lagrangean frame, or even to compute all fields in the current placement. Both formulations are challenging and heavily discussed in the literature. In this work, we propose another solution scheme that exploits the capabilities of advanced computational tools. Instead of amending the formulation, we can solve thermomechanics in the Lagrangean frame and electromagnetism in the Eulerian frame and manage the interaction between the fields. The approach is similar to its analog in fluid structure interaction, but more challenging because the field equations in electromagnetism must also be solved within the solid body while following their own different set of transformation rules. We additionally present a mesh-morphing algorithm necessary to accommodate finite deformations to solve the electromagnetic fields outside of the material body. We illustrate the use of the new formulation by developing an opensource implementation using the FEniCS package and applying this implementation to several engineering problems in electromagnetic structure interaction undergoing large deformations.

“…Multiplying by interpolation functions matrix N and integrating on the element, it is possible to find the nodal forces values for this element, (8) so the distributed force vector in the surface each element can be written as (9) Depending on the position of the MFC layer in the stack, and the curvature, the elemental force vector can contain only membrane contributions, or more likely also bending moments and shear forces.…”

Abstract. This paper presents a topology optimization methodology of piezoelectric actuators in laminated composite structures. The Linear Quadratic Regulator (LQR) optimal control technique is used. The topology optimization is formulated to find the optimum localization of the Macro Fiber Composite (MFC), through of the maximization of the controllability index. Actuator location optimization results show that the technique implemented improves the structural vibration damping.

“…Apart from this it should be also noted that the present ME structures comprise the piezoelectric fibers, i.e. MFC; the interdigitated electrodes of MFC deliver the electric field required to activate piezoelectricity in fibers to invoke the stronger piezoelectric effect along the length (effective in-plane poling direction) of the fibers (Kovalovs, Barkanov, and Gluhihs 2007). Thus, the piezoelectric fiber effects which are much more effective along the length of the fibers should be considered for present structures though they are of d 31 type.…”

Asymmetric and symmetric magnetoelectric (ME) laminates structures of piezoelectric macro-fiber composite (MFC)/nickel (Ni) were fabricated and investigated their ME and magneto-mechano-electric (MME) energy harvesting responses to an applied magnetic/ mechanical stimulations. Both the structures strongly revealed the dependence of ME voltage coefficient (α ME ) on applied magnetic field directions with an important feature of a zero-bias field ME response. This is much more beneficial for designing the magnetic field sensors. The fabricated MFC/Ni structures exhibited good energy harvesting response to applied simultaneous magnetic/ mechanical vibrations of lab magnetic stirrer. The electric power was successfully harnessed from magnetomechanical stimulations; the resulting potential and power were up to ,20 V p-p and ,6 μW respectively, which are quite enough power to light a commercial red LED with traditional rectifier circuit and capacitor. Hence, the present MFC/Ni ME generators provide their future feasibility having self-biasing feature for designing the magnetic field sensors as well as for powering small consumer electronic devices and wireless sensor network systems by exploiting mechanical/magnetic stimulations from surrounding.
