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, ...

Stress is a measure of the distribution of internal forces that develop within a body to resist these applied loads. There are two main types of stress - normal stress, which acts perpendicular to a ...

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 ...

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 ...
