粘弹性中的复数阶分数阶导数

Complex order fractional derivatives in viscoelasticity

Teodor M. Atanacković, Sanja Konjik, Stevan Pilipović, Dušan Zorica

摘要:

我们引入复数阶分数导数模型描述粘弹性材料。这不能无限制地进行,因此,我们得出,第一次,真正的价值相容性约束,以及物理约束,导致可接受的模型。因此,我们引入了一种新的形式的复阶分数阶导数。同时,我们考虑了一个具有复数导数的分数阶微分方程,并研究了它的可解性。应力松弛和蠕变得到的结果说明了几个数值例子。

英文摘要:

We introduce complex order fractional derivatives in models that describe viscoelastic materials. This can not be carried out unrestrictedly, and therefore we derive, for the first time, real valued compatibility constraints, as well as physical constraints that lead to acceptable models. As a result, we introduce a new form of complex order fractional derivative. Also, we consider a fractional differential equation with complex derivatives, and study its solvability. Results obtained for stress relaxation and creep are illustrated by several numerical examples.
