Insights into a thermodynamic duo could inform engineering decisions and improve the functionality of designs featuring elastic components. <\/p>\n\n\n\n

Nebraska physicist Christian Binek found that, under certain conditions, the magnetism of certain materials can predict the relationship between their temperature and elasticity. His finding could allow engineers to control the elasticity of those materials by strategically designing their magnetic properties or applying a magnetic field to them. <\/p>\n\n\n\n

\u201cRather than tuning the elastic properties by a magnetic field, you may be able to tune them by electric fields.\u201d\u00a0<\/p>Christian Binek<\/cite><\/blockquote>\n\n\n\n

Given how easily magnetic fields can be manipulated, Binek said, that could eventually mean tailoring elasticity in real time with the turn of a knob. <\/p>\n\n\n\n

In the meantime, knowing whether and how elasticity will respond to temperature changes may help engineers better select materials for specific purposes. Binek cited the disintegration of the Challenger space shuttle \u2013 caused by the temperature-induced hardening and failure of an elastic O-ring on its rocket booster \u2013 as evidence of elasticity\u2019s importance in engineering design. <\/p>\n\n\n\n

\u201cSo you can find materials that do not change (their) elastic properties with temperature,\u201d said Binek, professor of physics and astronomy. \u201cYou may find materials that change with temperature at will. And you may find materials where you can, at a given temperature, change the elastic properties by an external control.\u201d <\/p>\n\n\n\n

It\u2019s long been known that the laws of thermodynamics encompass the properties of magnetism and elasticity. By deriving a new formula from existing ones, Binek showed that the elasticity-temperature relationship is basically encoded in a material\u2019s magnetism. The formula might even apply to ferroelectric materials, whose alignment of positive and negative charges, or polarization, can be reversed by an electric field. <\/p>\n\n\n\n

    \u201cRather than tuning the elastic properties by a magnetic field, you may be able to tune them by electric fields,\u201d he said. \u201cTechnologically, that could be even more interesting. There are certainly many applications that one could think of, and I think many of them can be useful.\u201d <\/p>\n\n\n\n
