  • Analysis of concrete beams with partially bonded composite reinforcement 

    Lees, Janet Marillyn; Burgoyne, Christopher John (American Concrete InstituteACI Structural Journal, 2000)
    Beams prestressed with partially bonded fiber-reinforced plastic (FRP) tendons have high strength and rotation capacity but cannot be modeled by conventional techniques. Herein, it is assumed that all deformation takes ...

  • Analysis of delamination growth with discontinuous finite elements 

    Remmers, JJC; Wells, Garth Nathan; De Borst, R (Solids, Structures and Coupled Problems in EngineeringSolids, Structures and Coupled Problems in Engineering, 2001)
    In this contribution a new finite element is presented for the simulation of delamination growth in thin layered composite materials. The element is based on the solid-like shell element, a volume element that can be used ...

  • Analysis of delamination growth with discontinuous solid-like shell elements 

    Remmers, JJC; De Borst, R; Wells, Garth Nathan (International Journal of Numerical Methods in Heat and Fluid FlowInternational Journal of Numerical Methods in Heat and Fluid Flow, 2004)
    Delamination is one of the most important failure mechanisms in laminates. Normally, it is modelled using interface elements. These elements are placed between two layers that are modelled with continuum elements. The ...

  • Analysis of plasmid genes by phylogenetic profiling and visualization of homology relationships using Blast2Network 

    Brilli, Matteo; Mengoni, Alessio; Fondi, Marco; Bazzicalupo, Marco; Lio, Pietro; Fani, Renato (2008-12-21)
    Abstract Background Phylogenetic methods are well-established bioinformatic tools for sequence analysis, allowing to describe the non-independencies of sequences because of their common ancestor. However, the evolutionary ...

  • Anharmonic Acoustic Technique for Detection of Surface-bound Particles 

    Ghosh, Sourav Kumar (University of CambridgeDepartment of Engineering., 2011-07-12)
    Receptor-based biological detection techniques often suffer from the problem of non-specific interactions. This is largely due to the presence of weak electrostatic and Van der Waals forces between the receptor and the ...

  • Application of continuum laws in discontinuity analysis based on a regularised displacement jump 

    Wells, Garth Nathan; Sluys, LJ (Proceedings of the European Conference on Computational Mechanics ECCM '99Proceedings of the European Conference on Computational Mechanics ECCM '99, 1999)
    The application of continuum constitutive laws in embedded strong discontinuity analysis is examined. By adopting a regularised discontinuity (approximating the unbounded strain field resulting from a displacement jump ...

  • Application of mixed-integer programming in chemical engineering 

    Pogiatzis, Thomas (University of CambridgeDepartment of Chemical Engineering and Biotechnology, 2013-06-11)
    Mixed-Integer Programming has been a vital tool for the chemical engineer in the recent decades and is employed extensively in process design and control. This dissertation presents some new Mixed-Integer Programming ...

  • Atomic Layer Deposition of ZnO on Multi-walled Carbon Nanotubes and Its Use for Synthesis of CNT–ZnO Heterostructures 

    Unknown author (2010-08-07)
    Abstract In this article, direct coating of ZnO on PECVD-grown multi-walled carbon nanotubes (MWCNTs) is achieved using atomic layer deposition (ALD). Transmission electron microscopy investigation shows that the deposited ...

  • Autoignition in turbulent two-phase flows 

    Borghesi, Giulio (University of CambridgeDepartment of Engineering, 2013-01-08)
    This dissertation deals with the numerical investigation of the physics of sprays autoigniting at diesel engine conditions using Direct Numerical Simulations (DNS), and with the modelling of droplet related effects within ...

    Markides, Christos N; Mastorakos, Epaminondas (2009-05-21)
    The movie (taken with a conventional video camera at 30fps) shows the various operation modes of the Cambridge Autoignition experiment, described in: C.N. Markides, E. Mastorakos, An experimental study of hydrogen ...

  • Autoignition of droplets in hot air flow 

    Gordon, Robert; Mastorakos, Epaminondas (2010-09-09)
    A single-droplet generator has been used to inject fuel droplets of various sizes and chemical composition into a hot turbulent air flow. The ensuing autoignition and flame behaviour has been recorded with a fast camera. ...

  • Automated modelling of viscoelastic flow using FEniCS 

    Molari, L; Wells, Garth Nathan (XVI Convegno Italiano di Meccanica ComputazionaleXVI Convegno Italiano di Meccanica Computazionale, 2006)
    Using high-level abstractions, it is possible to efficiently automate the development of finite element models. This has advantages in terms of rapid development, a dramatic reduction in programming errors and offers the ...
