Deng, X. (author), Naeimi, M. (author), Li, Z. (author), Qian, Z. (author)

A modeling procedure to predict the residual fatigue life of rail at squats seeds is developed in this article. Two models are involved: a 3D explicit Finite Element (FE) model to compute the stress and strain at squats in rail, and the J-S fatigue damage model to determine the residual fatigue life on the basis of the computed stress and strain...

Influences of characteristic size of contact bodies on rolling contact

Qian, Z. (author), Deng, X. (author), Li, Z. (author), Dollevoet, R.P.B.J. (author)

The rolling contact of elastic bodies (upper body and lower body) can be analyzed with the Hertz theory and the Kalker’s model. It is generally believed that the width of the contact area should be much smaller than the characteristic size of each elastic body, to ensure that the half-space assumption is valid. However the definition of “much...

Development of engineered cementitious composites with limestone powder and blast furnace slag

Zhou, J. (author), Qian, S. (author), Sierra Beltran, M.G. (author), Ye, G. (author), Van Breugel, K. (author), Li, V.C. (author)

Nowadays limestone powder and blast furnace slag (BFS) are widely used in concrete as blended materials in cement. The replacement of Portland cement by limestone powder and BFS can lower the cost and enhance the greenness of concrete, since the production of these two materials needs less energy and causes less CO2 emission than Portland cement...

Applicability of half-space-based methods to non-conforming elastic normal contact problems

Deng, X. (author), Qian, Zhiwei (author), Li, Z. (author), Dollevoet, R.P.B.J. (author)

The half-space assumption has been employed in many solution methods for non-conforming contact problems in elasticity such as the Hertz theory and the Kalker's variational theory. It is generally believed that to guarantee acceptable accuracy in these half-space-based methods, the characteristic size (twice length of one semi-axis) of the...
