Failure theories are used to predict when a material will fail due to static loading. They do this by comparing the stress state at a point with material properties that can be easily determined from ...

Remarkably, nanopillars with a diameter of 70 nm and a twin spacing of 0.6 nm exhibit both ductile necking failure and a tensile strength of 2.4 GPa, a value that is higher than that measured for ...

The failure boundary in the σ P1 vs. σ P2 plane is given by: σ P1 / σ UT – σ P2 /σ UC = 1. The animation below shows how Mohr’s circle changes in position and size as we move around the perimeter of ...

Catastrophic failure. To test this, the researchers performed two experiments. ... the pillars became much more ductile, being compressible by more than 50% without any cracking. They then tried ...

There are more than 1,300 non-ductile concrete buildings currently identified by the city of Los Angeles, and nearly 13,000 soft-story buildings within city limits.
