ACELAN-COMPOS Package for Finite Element Simulation of Active Composite Materials- The ACELAN-COMPOS package is intended for computer design of two-phase active composite materials with the coupling of mechanical and electromagnetic fields. The most common class of such materials is the class of magnetoelectric (piezomagnetoelectric) composites. Other widely used examples of active composites are the piezoelectric composites consisting of a piezoelectric phase of one basic material and a piezoelectric or elastic phase of another material (possibly pores).
