Hadamard compatibility conditions for Rivlin–Ericksen tensors on weak singular surfaces
We consider weak singular surfaces in the sense of Hadamard and Thomas. The jump condition for the velocity gradient across such singular surfaces is well established and often used in the bifurcation analysis of localized deformation. In this paper, we present the jump conditions for the Rivlin–Ericksen tensors for the first time. With regards to a material motion, the jump conditions are derived for both propagating and standing singular surfaces. We showcase the geometric structure of strain acceleration discontinuities and the additional restrictions posed by incompressibility. It turns out, for standing (i.e. material) discontinuities the jumps of all higher-order Rivlin–Ericksen tensors depend nonlinearly on the jump of the velocity gradient. This enables a simple setting for the description of discontinuities in certain non-Newtonian constitutive models.
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.
