We study the effects of particle shape on the absorption and scattering cross sections of randomly oriented particles in the Rayleigh domain, i.e. particles that are very small compared to the wavelength of radiation both inside and outside the particle. In particular, we investigate the validity of the so-called statistical approach. In this approach it is assumed that the scattering and absor...

This article presents a theoretical and numerical study of bolted sleeve connections with rectangular hollow sections (RHS) under axial tension compression. The geometric form section provides resistance for high loads, torsion combines effects, spreading its utilization in truss systems. In this context, the proposed explore these characteristics RHS offer an attractive aesthetic appearance co...
