Abstract
In this presentation we discuss some issues about fractional partial differential equations of order between one and two appearing in viscoelasticity and thermoelasticity. In particular, we will look at simple strings, Euleur-Bernoulli beams and Timoshenko beams although our
arguments apply to many other types of problems. First, we justify the passage from integer order to fractional order. Then, we show how to prove well-posedness of the systems. Next, we establish some stability results. The main challenges and the difficulties encountered when dealing with the memory terms will be highlighted.
