  10. “Fractional Order Thinking” or, “In Between Thinking” • For example • Between integers there are non-integers; • Between logic 0 and logic 1, there is the “fuzzy logic”; • Between integer order splines, there are “fractional order splines” • Between integer high order moments, there are noninteger order moments (e.g. FLOS) • Between “integer dimensions”, there are fractal dimensions • Fractional Fourier transform (FrFT) – in-between time-n-freq. • Non-Integer order calculus (fractional order calculus – abuse of terminology.)

  19. Rule of thumb for Fractional Order Thinking • Porous media • Particulate • Granular • Lossy • Anomaly • Disorder • Soil, tissue, electrodes, bio, nano, network, transport, diffusion, soft matters (biox) … • Self-similar • Scale-free/Scale-invariant • Power law • Long range dependence (LRD) • 1/f a noise ME280 "Fractional Order Mechanics" @ UC Merced

  20. Fractional Order Mechanics: WHY? • Softmatter / hardmatter • Softbody / Rigidbody • Lumped / distributed • Granular, particulate, porous, disordered … materials • … ME280 "Fractional Order Mechanics" @ UC Merced

  21. Soft matter？ • Soft matters, also known as complex fluids, behave unlike ideal solids and fluids. • Mesoscopic macromolecule rather than microscopic elementary particles play a more important role. ME280 "Fractional Order Mechanics" @ UC Merced

  22. Typical soft matters • Granular materials • Colloids, liquid crystals, emulsions, foams, • Polymers, textiles, rubber, glass • Rock layers, sediments, oil, soil, DNA • Multiphase fluids • Biopolymers and biological materials highly deformable, porous, thermal fluctuations play major role, highly unstable ME280 "Fractional Order Mechanics" @ UC Merced

  27. Google says“Fractional Order Mechanics” ME280 "Fractional Order Mechanics" @ UC Merced

  28. G.W. Scott Blair (1950) • “We may express our concepts in Newtonian terms if we find this convenient but, if we do so, we must realize that we have made a translation into a language which is foreign to the system which we are studying.” ME280 "Fractional Order Mechanics" @ UC Merced
