In nonlinear elasticity, universal deformations are the deformations that exist for arbitrary strain-energy density functions and suitable tractions at the boundaries. Here, we discuss the equivalent problem for linear elasticity. We characterize the universal displacements of  linear elasticity: those displacement fields that can be maintained by applying boundary tractions in the absence of body forces for any linear elastic solid in a given anisotropy class.

The ability to transform the crystal structure of metals in the solid-state enables tailoring their physical, mechanical, electrical, thermal, and optical properties in unprecedented ways. We demonstrate a martensitic phase transformation from a face-centered-cubic (fcc) structure to a hexagonal-close-packed (hcp) structure that occurs in nanosecond timescale in initially near-defect-free single-crystal silver (Ag) microcubes impacted at supersonic velocities.

The Ira A. Fulton Schools of Engineering (FSE) at Arizona State University (ASU) and the School for Engineering of Matter, Transport and Energy are hiring faculty to support a broad initiative in manufacturing and biomanufacturing. In conjunction with that initiative, we seek applicants for tenure-track/tenured faculty positions in the areas of manufacturing of advanced materials (metals, polymers, ceramics, semiconductor, and composites) and biomanufacturing/biofabrication (biomolecules, biomaterials, cells and tissues).

In "Littlewood's Miscelleny" the celebrated mathematician John E. Littlewood noted that a hoop with an attached mass rolling on a ground plane may exhibit self-induced jumping. Subsequent works showed that his analysis was flawed and revealed paradoxical behavior that can be resolved by incorporating the inertia of the hoop. In our newly published paper in the Transactions A of the Royal Society tinyurl.com/littlewood-hoop  a comprehensive analysis of the dynamics of the hoop is presented.
