FE software packages for modeling mechanical structures formulate model elements and nodes differently, but often arrive at very similar results FEA software has converged on three types of elements.

Understanding how helical, curved beams operate — how their spiral cuts accommodate angular and parallel misalignment, axial motion, and system vibrations — is the key to knowing how they will perform ...

Lasers may have thousands of applications in every section of modern society, but all laser beams are fundamentally similar – single-coloured and straight. Now, US physicists have helped to break that ...
