Disorder-induced stress–flow misalignment in soft glassy materials revealed using multidirectional shear

Proceedings of the National Academy of Sciences, Volume 123, Number 4, January 2026.
ImportanceThe mechanical properties of soft vitreous materials (such as toothpaste or mayonnaise) are essential, for example, to 3D printing or medical applications. They are viscoelastic solids at rest but flow as liquids above a stress threshold due to a disordered system…
