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.

BUFFALO, N.Y. — In a physics first, a team including scientists from the University at Buffalo and the National Institute of Standards and Technology (NIST) has created a way to make beams of neutrons ...

Physicists have demonstrated accelerating light beams on flat surfaces, where acceleration has caused the beams to follow curved trajectories. However, a new experiment has pushed the boundaries of ...

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 ...

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 ...

Airy beam: When an ordinary beam of neutrons strikes the team’s silicon grating, the millions of scored lines on the grating convert the neutrons into an Airy beam with a wavefront that travels along ...

Scientists have created the first neutron 'Airy beam,' which has unusual capabilities that ordinary neutron beams do not. The achievement could enhance neutron-based techniques for investigating the ...
