In the past few decades, fractional derivatives have been recognized as powerful modelling and simulation tools for mechanical engineering problems. Many physical laws are expressed more accurately in terms of differential equations of arbitrary order.  In this Special Issue, we kindly invite researchers to present their original work in the area of fractional differential equations as models of complex engineering problems. These works may bring new theories, development of numerical methods, and applications. All research articles should fit the scope of the journal Computers, Materials & Continua, and topics of interests include (but are not limited to):

· Mathematical modelling of complex engineering problems using fractional differential

equations

· Artificial intelligence and data analysis within fractional calculus methods and techniques

· Advanced analytical and numerical methods for fractional differential equations

· Real world applications of fractional models in engineering

· Mathematical modeling of engineering fractional dynamic systems

· Computational and numerical methodologies for fractional differential equations with engineering meaning
