Abstract
Actuator is a mechatronic system that transforms one type of energy (e.g.
electric energy) into the mechanical displacement and mechanical force (mechanical energy).
Nowadays, these actuators can be made of Functionally Graded Materials (FGM)
to ensure simple shape of the actuator and to improve its effectiveness, particularly for
micro systems. FGM is built as a mixture of two or more constituents which have almost
the same geometry and dimensions. The variation of macroscopic material properties can
be induced by variation of both the volume fractions and material properties (e.g. by a
non-homogeneous temperature field) of the FGM constituents.
The paper deals with a new approach in analysing of the systems made of FGM using
our new beam finite elements. Multiphysical analysis (weak coupled electro-thermomechanical
analysis) and spatial continuous variation of material properties are supported.
The analysis of the micro actuator with constant cross section made of FGM is presented
in the paper. This simple-shaped actuator is supplied by electric current and the efficiency
of the actuator is optimised. The solution results will be compared with those obtained
by using solid elements of a FEM commercial program.
