Disordered solids are materials in which the atoms are not arranged in a regular pattern. This lack of order can lead to a number of interesting and unexpected properties, such as the ability to deform in a highly nonlinear way.
In their study, the EPFL physicists developed a new mathematical framework to describe the deformation of disordered solids. The framework is based on the idea that the deformation of these materials can be understood by considering the interactions between individual atoms.
The researchers used their framework to study the deformation of a model glass. They found that the glass deformed in a highly nonlinear way, and that the deformation was very sensitive to the interactions between the atoms.
The results of the study could help to improve the design of materials such as glass, ceramics, and metals. By understanding how these materials deform, engineers can design materials that are stronger and more durable.
"Our work provides a new way to understand the deformation of disordered solids," said Professor Andrea Liu, who led the research. "This could help to improve the design of materials such as glass, ceramics, and metals, and could also lead to new insights into the behavior of other disordered materials."
