\b[Boban Tanovic] contributed to the MATTER educational software for <materials science>. The project’s user guide names him in its Design and Development Team; the mechanics module credits Tanovic alongside <Bill Clyne>.<Materials Science on CD-ROM user guide by the MATTER Project>[Printed p. 4, project credits]{ref}<Mechanics of Composite Materials by Bill Clyne and Boban Tanovic>[Module heading and credits]{ref}
The module turns <composite material> models into interactive comparisons. Its load-transfer section contrasts the equal-<strain> <longitudinal rule of mixtures> with the equal-<stress> <isostress rule of mixtures>, letting a learner vary constituent moduli and proportions. The educational point is scientifically useful: two predictions can differ because they impose different geometries and load-sharing assumptions, even with the same constituent data.<Mechanics of Composite Materials by Bill Clyne and Boban Tanovic>[Load Transfer, model comparisons and parameter exploration]{ref}
For instance, an illustrative mixture with equal volumes of phases having <Young's moduli> $10$ and $100\,\mathrm{GPa}$ gives $55\,\mathrm{GPa}$ in the ideal equal-<strain> case but about $18.2\,\mathrm{GPa}$ in the ideal equal-<stress> case. Changing a model assumption changes the answer; interacting with such a comparison helps distinguish a model prediction from a measured material property.
