If the Poisson’s ratio of the material if positive, then tensile/compressive strains in the x-direction produce compressive/tensile strains in the y- and z-directions, as shown below. Negative Poisson ...

Thermal and mechanical stresses are creating significant challenges in heterogeneous chiplet assemblies, increasing the time and cost required to work through all the possible physical effects, ...

New research shows that the electronic structure of metals can strongly affect their mechanical properties. New research from the University of Birmingham shows that the electronic structure of metals ...
