Effect of magnetostrictive material layer on the stress and deformation behaviour of laminated structure

In the present investigation, static bending and strength behaviour of the laminated composite plate embedded with magnetostrictive (MS) material has been computed numerically using commercial finite element tool. For the analysis purpose, a simulation model of the laminated plate embedded with and without MS material is derived using the batch input technique popularly termed as ANSYS parametric design language (APDL). The MS bonded composite model is discretised with the help of available suitable element from ANSYS element library. The elements are chosen suitably by considering the compatibility between the mechanical and the magnetic fluxes indices. For the calculation of the necessary responses, APDL code has been prepared in ANSYS environment. Further, the stability of the model has been checked by computing the responses for various mesh sizes. Subsequently, the accuracy of the model has also been checked by conducting the comparison test. For the comparison, central deflection of the clamped Graphite/Epoxy laminated plate embedded with Terfenol-D has been evaluated and compare them with those of the available earlier published literature. The comparison study clearly indicates that, the present responses are in-line and showing good agreement with that of the reference. Further, the versatility and the applicability of the simulation model has been proven by solving the different illustrations. In the illustration, the influence of the different geometrical parameter such as thickness ratio and aspect ratio on the bending behaviour has been investigated and discussed in detail. (paper)
