“…Application of an electric current results in the Joule heating with density (5). The plate is also immersed in a constant in-plane magnetic field = constant (8) As for the boundary conditions, it is assumed that the plate is simply supported (9) It is also assumed that the electric current is applied to the composite plate through the copper bar electrodes attached to the short 031004-2 / Vol. 134, JULY 2012 Transactions of the ASME sides of the plate, which results in a non-negligible contact resistance heating with density qc.…”

“…The mechanical and electromagnetic loads were assumed to be coordinated so that the maximum of the impact load and the peak of the applied current occur at the same time (i.e., Xc = Xp = 10ms). Figure 6 shows the transverse middle plane deflection, w, at the center of the plate (j = 0) as a function of time for different combinations of the electromagnetic loads consisting of the pulsed current (7) and the constant magnetic field (8).…”

“…This coupling mechanism can potentially lead to the development of structures amenable to active control by the electromagnetic field. However, highintensity or long-duration applications of the electromagnetic loads lead to significant heating that may result in the development of thermal stresses and degradation of the mechanical properties, if the temperature in a polymer matrix composite exceeds the glass transition temperature [8][9][10][11][12]. One possible way to mitigate the negative effects of the current-induced heating observed in experiments on electrified composites subjected to a high DC current [9] is to apply electromagnetic loads of high intensity but short duration (i.e., pulsed electromagnetic loads).…”

Thermal and mechanical response of a carbon fiber polymer matrix composite plate subjected to a transverse impact and in-plane pulsed electromagnetic loads is studied. Heat transfer analysis in the electrified composite plate for the electric currents of various waveforms (direct current (DC), alternating current (AC), and pulsed) is conducted, and the effects of the waveform parameters (characteristic time, peak, etc.) on the currentinduced heating in the composite are investigated. The results show that pulsed electric currents cause significant temperature rises only in the regions immediateiy adjacent to the electric contact (composite-electrode interface). As for the mechanical response of the composite piate, it is found that the characteristics of the electromagnetic field (waveform, duration of application, and intensity) can significantly reduce deflection and stresses in the plate, and concurrent application of a pulsed electromagnetic load can effectively mitigate the effects of the impact load in the electrically conductive composites.

“…Rothe et al [55] have considered Electro-Thermo-Elasticity in a small strain setting, where they have focused on the numerical treatment of the monolithic approach, with the development of a one dimensional analytical solution in the purpose of code verification. In particular Zhupanska et al [74] have discussed the governing equations describing electromagnetic, thermal, and mechanical field interactions. Nevertheless these contributions are still limited to small deformation settings.…”

A coupled Electro-Thermo-Mechanical Discontinuous Galerkin (DG) method is developed considering the non-linear interactions of electrical, thermal, and mechanical fields. In order to develop a stable discontinuous Galerkin formulation the governing equations are expressed in terms of energetically conjugated fields gradients and fluxes. Moreover, the DG method is formulated in finite deformations and finite fields variations. The multi-physics DG formulation is shown to satisfy the consistency condition, and the uniqueness and optimal convergence rate properties are derived under the assumption of small deformation. First the numerical properties are verified on a simple numerical example, and then the framework is applied to simulate the response of smart composite materials in which the shape memory effect of the matrix is triggered by the Joule effect.

To shorten the preparation cycle of Al/PEEK/CFRP laminates fabricated by Al sheets, peek films, and CFRP prepreg and reduce energy consumption during the preparation process to ensure the highest quality laminates, a novel forming process based on self-resistance electric (SRE) heating was proposed. Considering the tensile properties, fracture morphology, and void content comprehensively, the influence of current intensity (11.5, 12.5, 13.5 A) on the forming quality of laminates was explored. This optimized electric heating process was compared with the traditional heating process with respect to forming time, energy consumption, and the performance of the prepared samples. The results show that when the current is 12.5 A, the molding quality of the samples prepared by the SRE process is better than that of the traditional process.In addition, the SRE process significantly reduces forming times and saves energy. This SRE heating method provides a new process optimization pathway for the preparation and formation of fiber metal laminates and exhibits great prospects for future research.
