TY - JOUR TI - A new general fractional derivative relaxation phenomenon AU - Yang Xiao-Jun AU - Alsolami Abdulrahman Ali AU - Nadeem Sohail D JN - Thermal Science PY - 2023 VL - 27 IS - 1 SP - 721 EP - 726 PT - Article AB - This article addresses a novel anomalous relaxation model with the new general fractional derivative of the Sonine kernel. This operator is considered in the sense of general fractional derivative proposed in the work [Yang et al., General fractional derivatives with applications in viscoelasticity, Academic Press, New York, USA, 2020]. The solution of the mathematical model is obtained with the aid of Laplace transform. The comparison among the classical and anomalous relaxation models is discussed in detail. This result is proposed as a mathematical tool to model the anomalous relaxation behavior of the complex materials.
