Zhao, T. (author), Palardy, G. (author), Villegas, I.F. (author), Rans, C.D. (author), Martinez, M.J. (author), Benedictus, R. (author)The in-plane and out-of-plane mechanical behaviour of both ultrasonically spot-welded and mechanically fastened joints was investigated by double-lap shear and pull-through tests, respectively. Spot-welded specimens showed comparable onset failure load and significantly higher joint stiffness compared to mechanical fasteners when carrying shear...journal article 2016

Zhao, T. (author), Palardy, G. (author), Rans, C.D. (author), Benedictus, R. (author)Ultrasonic welding is a promising assembly technique for thermoplastic composites and it is well-suited for spot welding. In this paper, the in-plane and out-of-plane mechanical behaviour of ultrasonically spot-welded and mechanically fastened joints are investigated by double-lap shear and pull-through tests, respectively. Special attention was...conference paper 2016

Taal, A. (author), Itard, L.C.M. (author), Zeiler, W. (author), Zhao, Y (author)A much occurring problem in the Energy Management Systems of existing buildings and HVAC services is that the measurements are unreliable. In this article a methodology is described which can be used to determine the presence of errors in energy monitoring, caused by faulty measurements. These errors can be detected and subsequently diagnosed....conference paper 2016

Zhao, D (author), Asadi, Kamal (author), Groen, W.A. (author), Blom, PWM (author), de Leeuw, D.M. (author)A homogeneous ferroelectric single crystal exhibits only two remanent polarization states that are stable over time, whereas intermediate, or unsaturated, polarization states are thermodynamically instable. Commonly used ferroelectric materials however, are inhomogeneous polycrystalline thin films or ceramics. To investigate the stability of...journal article 2016

Zhao, J. (author), Vollebregt, E.A.H. (author), Oosterlee, C.W. (author)In this paper we extend the range of applicability of the boundary element method (BEM) for concentrated elastic contact problems by computing the influence coefficients (ICs) numerically. These ICs represent the Green's function of the problem, i.e. the surface deformation due to unit loads. For the half-space they are analytically available....report 2015

Zhao, X. (author), Verhagen, W.J.C. (author), Curan, R. (author)n an integrated aircraft design and analysis practice, Life Cycle Cost (LCC) is essential for decision making. The LCC of an aircraft is ordinarily partially estimated by emphasizing a specific cost type. However, an overview of the LCC including design and development cost, production cost, operating cost and disposal cost is not provided. This...book chapter 2015

Zhao, J. (author)Rail transportation plays an important role in our everyday life, and there is fast development and modernization in the railway industry to meet the growing demand for swifter, safer and more comfortable trains. At the same time, the security of train operation and the maintenance of rails have to be considered. A lot of research on these...doctoral thesis 2015

Zhao, G. (author), Lu, J (author), Visser, P.J. (author)The fluvial river is a kind of open system that can interact with its outside environments and give response to disturbance from outside on the earth. It can adjust itself to the disturbances outside the system and reflects new characteristics in the process of reaching a new equilibrium. The TGD (Three Gorges Dam) constructed at the Yangtze...journal article 2015

Zlatanova, S. (author), Liu, L. (author), Sithole, G. (author), Zhao, J. (author), Mortari, F. (author)This report makes an overview of 2D, 2,5D and 3D approaches for indoor space subdivision for the purpose of indoor navigation. The report starts with a conceptual framework for indoor space utilisation. We introduce and elaborate on the concepts of indoor space (navigable and non-navigable), agent, activity, resource and modifier. Using these...report 2014

Biljecki, F. (author), Ledoux, H. (author), Stoter, J.E. (author), Zhao, J. (author)The level of detail in 3D city modelling, despite its usefulness and importance, is still an ambiguous and undefined term. It is used for the communication of how thoroughly real-world features have been acquired and modelled, as we demonstrate in this paper. Its definitions vary greatly between practitioners, standards and institutions. We...journal article 2014

(author)The martensitic transformation behaviour of the metastable austenite phase in low-alloyed transformation-induced plasticity (TRIP) steels has been studied in situ using high-energy X-ray diffraction during deformation. The austenite stability during tensile deformation has been evaluated at different length scales. A powder diffraction analysis...journal article 2014

Zhao, J. (author), Vollebregt, E.A.H. (author), Oosterlee, C.W. (author)This paper presents a fast numerical solver for a nonlinear constrained optimization problem, arising from a 3D frictional contact problem. It incorporates an active set strategy with a nonlinear conjugate gradient method. One novelty is to consider the tractions of each slip element in a polar coordinate system, and use azimuth angles as...report 2014

Zhao, G. (author), Visser, P.J. (author), Peeters, P. (author)Embankment breaching is a composite process coupled by hydraulic processes and sediment transport processes. Erosion is the link in the interaction between breach flow and embankment material. Surface erosion starts in the initial breach phase and triggers the initial damage of the embankment. As the surface erosion develops completely, the...report 2014

Zhao, Z. (author), Ledoux, H. (author), Stoter, J.E. (author)The LoD2 building models defined in CityGML are widely used in 3D city applications. The underlying geometry for such models is a GML solid (without interior shells), whose boundary should be a closed 2-manifold. However, this condition is often violated in practice because of the way LoD2 models are constructed and exchanged. Examples of the...conference paper 2013
