2. Graphical representation of energy transfer

This section introduces the first graphical conventions for link graphs. The graphical language of link graphs is enriched by the results of research. The conventions indicated here correspond to those commonly accepted by the international community at the time of publication. The work of this community is shared every two years at the International Conference on Bond Graphs and Modeling (ICBGM).

Readers may come across works in the literature that propose a different graphic symbolism, sometimes using a different vocabulary. We have tried to use the most common notations.
