Implementation of Creep Model with Fractional Derivative in FLAC3D

The fractional derivative element is a physical model, which has a physical meaning and can describe accurately the creep law. FLAC3D is a finite difference software and often used in numerical simulation of geotechnical engineering. This paper studied the realization of creep model with fractional derivative in FLAC3D by Burger model and FISH procedural language. This dissertation researches numerical simulation of fractional derivative element has an important reference value and significance.
