Determination of the Radiation Exchange Factor in the Bundle of Steel Round Bars

Energies, 2021
A method to obtain a radiation exchange factor FR in the bundle of steel round bars is presented. This parameter is required for determination of the radiative thermal conductivity krd, which is one of the basic thermal properties of the bar bundles.

Evolution of crack paths and compliance in round bars under cyclic tension and bending [PDF]

Fracture and Structural Integrity, 2014
The aim of this paper is to calculate how the surface crack front and the dimensionless compliance evolve in cracked cylindrical bars subjected to cyclic tension or bending with different initial crack geometries (crack depths and aspect ratios). To this
