Доклад на тема:

Zener model with General fractional calculus: Thermodynamical Restrictions

ще изнесат Teodor M. Atanackovic и Stevan Pilipovic, Serbian Academy of Sciences and Artand University of Novi Sad, Serbia.

Поканват се всички интересуващи се.

Резюме. We study a Zener type model of viscoelastic body within the context of general fractional calculus and derive restrictions on coefficients that follow from the dissipation inequality that is, the entropy inequality under isothermal conditions. We show, for a stress relaxation and a wave propagation, that the restrictions that follow from the entropy inequality are sufficient to guarantee the existence and uniqueness of the solution. We present numerical data related to the solution of a wave equation for several values of parameters.

This talk is part of the work program of a project (2020-2022) under the bilateral collaboration between the Bulgarian Academy of Sciences and the Serbian Academy of Sciences and Arts.
