Purpose. In the research one should do: 1) to determine a 3-d stress-strain state of the rail head in contact with the rolling wheels; 2) to analyze different forms of contact interaction; 3) to obtain the data necessary to calculate the durability of rai... see more

The tendencies of application of modern digital technique for carrying out the experimental research of the rolling stock effect on the track are shown. The possibility of determination of the elasticity module of the basis under a rail by results of meas... see more

The surface integrity of any manufactured product produced in machining process has proved to have a significant impact on the performance of the product. Many parameters influence the integrity of the surface, few of which are microstructure of the mater... see more

The present study proposes three strengthening solutions for wide flange steel beams having residual stresses and initial imperfections. In Solution 1, a midspan web stiffener is applied to such beams, aiming at reducing local web buckling. In Solution 2,... see more

Elastic and inelastic moment resistances of W-steel beams with considering the effects of initial imperfections and residual stresses are numerically investigated in the present study. The numerical model is implemented in ABAQUS in which residual stresse... see more
