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, ...
The entire stress-strain curve can now be determined using nanoindentation with a flat-ended cylindrical punch and novel analysis of the resulting force-displacement data 1. Unlike pyramidal indenters ...
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 ...
