DOI: 10.1016/j.probengmech.2018.05.003

Abstract: Abstract This paper specifies the multiple timescale spectral analysis to the structural analysis of a single degree-of-freedom structure including a fractional derivative constitutive term. Unlike usual existing models for this kind of structure, the excitation… read more here.

DOI: 10.1039/d0sm00354a

Abstract: Soft materials often exhibit a distinctive power-law viscoelastic response arising from broad distribution of time-scales present in their complex internal structure. A promising tool to accurately describe the rheological behaviour of soft materials is fractional… read more here.
