The normal and shear components of the stress tensor on octahedral planes are called octahedral normal stress and octahedral shear stress respectively. ... more

In science, buckling is a mathematical instability that leads to a failure mode.

When a structure is subjected to compressive stress, buckling may ... more

The center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero.
