Georget, Fabien (author), Wilson, William (author), Soja, Wioletta (author), Zheng, Junjie (author), Scrivener, Karen (author)Quantitative predictions for durability issues are necessary to adapt the formulations of cement blends with novel supplementary cementitious materials. These predictions are usually carried out with reactive transport models which are solved at the macroscopic scale. Upscaling laws are necessary to ensure that effective transport properties...conference paper 2021

Li, Yan (author), Draycott, Samuel (author), Zheng, Yaokun (author), Lin, Zhiliang (author), Adcock, Thomas A.A. (author), van den Bremer, T.S. (author)Abrupt depth transitions (ADTs) have recently been identified as potential causes of 'rogue' ocean waves. When stationary and (close-to-) normally distributed waves travel into shallower water over an ADT, distinct spatially localized peaks in the probability of extreme waves occur. These peaks have been predicted numerically, observed...journal article 2021

Zheng, Li (author), Kumar, Siddhant (author), Kochmann, Dennis M. (author)We present a two-scale topology optimization framework for the design of macroscopic bodies with an optimized elastic response, which is achieved by means of a spatially-variant cellular architecture on the microscale. The chosen spinodoid topology for the cellular network on the microscale (which is inspired by natural microstructures...journal article 2021

Zheng, X. (author), Pisano, F. (author), Vardon, P.J. (author), Hicks, M.A. (author)This paper presents a single-point Material Point Method (MPM) for large deformation problems in two-phase porous media such as soils. Many MPM formulations are known to produce numerical oscillations and inaccuracies in the simulated results, largely due to numerical integration and stress recovery performed at non-ideal locations, cell...journal article 2021

Zheng, Y. (author), Shyrokau, B. (author), Keviczky, T. (author)The public acceptance of automated driving is influenced by multiple factors. Apart from safety being of top priority, comfort and time efficiency also have an impact on the popularity of automated vehicles. These two factors contradict each other as optimizing for one results in the degradation of the other. We investigate in this paper how...conference paper 2021

Zhang, Qingzhou (author), Zheng, Feifei (author), Jia, Yueyi (author), Savic, Dragan (author), Kapelan, Z. (author)Real-time hydraulic modelling can be used to address a wide range of issues in a foul sewer system and hence can help improve its daily operation and maintenance. However, the current bottleneck within real-time FSS modelling is the lack of spatio-temporal inflow data. To address the problem, this paper proposes a new method to develop real...journal article 2021
