Methods for determination of residual stress in rail
(Faculty of Mechanical Engineering, Niš, 2018)
The residual stresses in rails are generated during the manufacturing process and have uneven distribution in rail cross section. The residual stress is a part of basic tensile stress in rail foot. For used rail, the ...
Railway/Road Level Crossing Design - Aspect of Safety and Environment
(Springer Verlag, 2018)
At the railway/road level crossings, two essentially different modes of transport intersect, both with a variety of vehicle performance parameters and traffic organization rules. Level crossing presents a collision zone ...
Influence of acid treatment and carbonation on the properties of recycled concrete aggregate
(Savez hemijskih inženjera, Beograd, 2018)
Recycled concrete aggregate (RCA), obtained by crushing of original (old) concrete, consists of natural aggregate grains and a cement mortar matrix. The presence of old adhered cement mortar, which has higher porosity than ...
