Abstract

A non-ordinary state-based peridynamic model(NOSBPD) is presented for linear piezoelectromagnetic material(PEM). The corresponding material model is developed by establishing the connection between the classical theory of piezoelectromagnetics and the newly proposed peridynamic framework. The variational approach and Hamiltonian principle are utilised to establish the equation of motion. This investigation shows the effectiveness of the proposed model to handle piezoelectromagnetic material. It is also shown that the considered stabilisation method effectively reduces the instabilities of NOSBPD. The dynamic behaviour of piezoelectromagnetic material in the proposed framework is investigated. The dispersion relations for stabilised versions of NOSBPD in one and two dimensions are established analytically for PEM. The graphs illustrate the influence of δ and different nonlocality functions on frequency, phase velocity, and group velocity. Also, the significant impact of critical coupling parameters on frequency is studied using graphical demonstration. Piezoelectromagnetic materials are used in a wide range of applications to constitute transducers such as actuators and sensors. Gaining insight into their wave and vibrational properties is indispensable for the advancement of reliable and optimised devices.

期刊介绍： The International Journal of Engineering Science is not limited to a specific aspect of science and engineering but is instead devoted to a wide range of subfields in the engineering sciences. While it encourages a broad spectrum of contribution in the engineering sciences, its core interest lies in issues concerning material modeling and response. Articles of interdisciplinary nature are particularly welcome. The primary goal of the new editors is to maintain high quality of publications. There will be a commitment to expediting the time taken for the publication of the papers. The articles that are sent for reviews will have names of the authors deleted with a view towards enhancing the objectivity and fairness of the review process. Articles that are devoted to the purely mathematical aspects without a discussion of the physical implications of the results or the consideration of specific examples are discouraged. Articles concerning material science should not be limited merely to a description and recording of observations but should contain theoretical or quantitative discussion of the results.
