Khatod has released two interesting lens families, with very narrow and very rectangular beams. One family is called ‘clean rectangular beam’. “Most lenses for LED applications in current use produce ...

A direct asymptotic integration of the full three-dimensional problem of elasticity is employed to derive a consistent governing equation for a beam with the rectangular cross section. The governing ...

The critical load causing secondary failure of a deep beam by lateral buckling may be calculated by standard methods for those cases in which the beam behaves elastically under the applied load. When, ...
