“…Methods can be basically divided into substitution methods [crack opening displacement method (Aliabadi and Rooke, 1991), extrapolation methods based on stress field (Parteymüller, 1999) or displacement field around the crack tip (Owen and Faweks, 1983), one-point or twopoint displacement method (Lim et al, 1992)] and energy methods [virtual crack closure method (Buchholz et al, 1987), virtual crack extension method (Hellen and Blackburn, 1975), J-integral (Aliabadi and Rooke, 1991), etc.]. Due to their robustness and accuracy the displacement methods are most often used to determine the fracture parameters for the problems of cracks propagation simulation under contact conditions (Chue and Chung, 2000;Ko et al, 2001;Ren et al, 2002;Ringsberg and Bergkvist, 2003). The quarter point displacement (QPD) method was used in this paper, where the stress intensity factors are determined from displacements on opposite crack surfaces by the following relationships (Lim et al, 1992): …”

“…The maximum tangential stress (MTS), proposed by Erdogan and Sih (1963), and the minimum strain energy density (SED) criterion, proposed by Sih (1974), are often used for crack propagation analysis in lubricated or dry contact area (Keer and Bryant, 1983;Kaneta et al, 1985;Bower, 1988;Chue et al, 2000;Datsyshyn and Panasyuk, 2001;Ko et al, 2001;Frolish et al, 2002;Ren et al, 2002). Most of the cited research work considers only the influence of K I and K II stress intensity factors on crack propagation, which is a valid assumption for long cracks.…”

Modelling of Surface Crack Growth under Lubricated Rolling–Sliding Contact Loading

The paper describes modelling approach to computational simulation of surface crack growth subjected to lubricated rolling-sliding contact conditions. The model considers the size and orientation of the initial crack, normal and tangential loading due to rolling-sliding contact and the influence of fluid trapped inside the crack by a hydraulic pressure mechanism. The motion of the contact sliding load is simulated with different load cases. The strain energy density (SED) and maximum tangential stress (MTS) crack propagation criteria are modified to account for the influence of internal pressure along the crack surfaces due to trapped fluid. The developed model is used to simulate surface crack growth on a gear tooth flank, which has been also experimentally tested. It is shown that the crack growth path, determined with modified crack propagation criteria, is more accurately predicted than by using the criteria in its classical form.

“…Further, the cracks are partially filled with slag which enhances the pressure distribution within the cracks-crack closing www.steel-research.de mechanisms are obstructed-the different thermal expansion coefficient of slag and steel enhances wear due to higher local pressures. [10] At the inner lip of the upper ring (Figure 11e,f), highly deformed zones resulting from contact sliding during the drop out of solidified slag are visible (the red arrow marks the sliding direction of the solidified slag). Due to the relatively high deformation within this zone, cracks are visible at the upper ring throughout the whole diameter.…”

The containers used for steel slag transportation to the recycling depot undergo hightemperature gradients and often deform plastically. Also, parts of the thereby solidified slag adhere to the pot walls, causing demolding problems and wear. A thorough finiteelement analysis of the heat transfer, initiated by filling the pots and essentially driven by radiation, and the thermal stresses is performed. Due to periodic fill-in and discharge, these are assumed to admit a quasi-stationary state referring to the pot temperature before their emptying. The so obtained results aid optimizing the pot shape and the transport process in terms of minimizing maintenance and anti-adhesive cladding. A layer of solidified slag is found to exist throughout the transport process. Although the phase change occurs almost instantaneously at a liquid-solid interface, the "mushy zone" is considered in the accompanying analytical study of the associated Stefan-type problem. Good correlations of the predicted temperatures to the measured ones and the resultant surface damaging are obtained.

“…CFRP can be a suitable reinforcement material to repair post-heated RAC in numerous engineering applications. ABAqUS software [25][26][27] was used to conduct analysis of STSRCs subjected to axial compressive after exposure to 500°C and repaired by CFRP. FEA modelling was then used to investigate the stress state of each partial failure location.…”

This paper presents the results of experimental investigations on steel tube strengthened recycled concrete (STSrC) exposed to high temperatures and reinforced by CfrP. The failure mode, bearing capacity and deformability of the columns were investigated to analyze the effects of CfrP, temperatures (300°C, 500°C and 700°C), and recycled coarse aggregate (rCa) replacement ratios (0%, 50% and 100%) on mechanical performance. The results indicate that the higher exposed temperatures, the more cracks occurred and the lower ultimate load carrying capacities for the specimens, and the failure mode and load capacity could be increased greatly by external strengthened with CfrP sheets. however, the higher rCa replacement ratio could induced a smaller cracks and higher load capacity, and the specimens with 50% rCa ratio gave the highest load capacity when exposed to high temperature. in addition, the ABAQUS software was employed to conduct finite element analysis (FEA) of STSRC reinforced, and a comparison of results calculated using the proposed model exhibits good agreement with an experimental results.
