  • The dynamic cutting of metals 

    Smith, J D (University of CambridgeEngineering Laboratory, 1962)
    Prediction of regenerative machine tool chatter requires a knowledge of the cutting forces existing under vibration conditions. Previous direct experimental work has been very limited in its range and has given results ...


  • Fundamental and applied aspects of contact electrification 

    Elsdon, Ronald (University of CambridgeDepartment of Chemical Engineering, 1976-02)
    Apparatus has been developed, which permits the measurement of electrification produced by rolling or sliding contact between a spherical specimen, and a plane dielectric sample. Measurements of the charge transferred to ...

  • Vortex flow around the bases of obstacles 

    Baker, Christopher James (University of CambridgeSt. Catharine's CollegeDepartment of Engineering, 1979-02-06)
    This thesis presents the results of experimental and theoretical investigations of the horseshoe vortex systems caused by boundary layer separation upstream of obstacles mounted on a wall. Flow visualization enabled these ...

  • The elastic and plastic behaviour of cellular materials 

    Gibson, Lorna Jane (University of CambridgeChurchill CollegeDepartment of Engineering, 1981-11-10)
    Cellular materials are widespread. Some, like wood and bone, occur in nature, while others, like polymeric foams, are manmade. Because of their cellular structure, they have unusual mechanical properties: they can be stiff, ...

  • Shear strength of reinforced concrete wall-beam structures: upper- bound analysis and experiments 

    Bin Mohamed, Zainai (University of CambridgeDowning CollegeDepartment of Engineering, 1987-10-27)
    This study presents rigid-plastic methods of analysis of shear failure in reinforced concrete (R. C.) wall-beam type structures when subjected to in-plane loading. The upper-bound approach is emphasised. Present shear ...

  • Scale effects in tests on footings 

    Lau, Chi Keung (University of CambridgeChrist's College, 1988-02-21)
    This dissertation presents an investigation of the effects of stress, and of absolute and relative particle size, in tests on vertically loaded footings. Two granular materials, namely, a silica rock flour and a Chatelet ...

  • Friction and lubrication in metal rolling 

    Sutcliffe, Michael Patrick Forbes (University of CambridgeJesus CollegeDepartment of Engineering, 1989-11-14)
    This dissertation is concerned with the physical processes which determine friction and lubrication in metal rolling in the mixed lubrication regime, with particular attention paid to the conditions encountered when rolling ...

  • Adaptive techniques in signal processing and connectionist models 

    Lynch, Michael Richard (University of CambridgeDepartment of EngineeringChrist's College, 1990-11-13)
    This thesis covers the development of a series of new methods and the application of adaptive filter theory which are combined to produce a generalised adaptive filter system which may be used to perform such tasks as ...

  • Planning multisentential English text using communicative acts 

    Maybury, Mark Thomas (University of Cambridge, 1991-11-12)
    The goal of this research is to develop explanation presentation mechanisms for knowledge based systems which enable them to define domain terminology and concepts, narrate events, elucidate plans, processes, or propositions ...

  • Cross-sector policy research: insights from the UK energy and transport sectors 

    Peake, Stephen Robert (University of CambridgeDepartment of Engineering, 1993-10-26)
    Following established traditions in anthropology and sociology, where cross-border research helps to identify important themes which benefit from comparative study, this dissertation introduces cross-sector policy research ...

  • Face recognition using Hidden Markov Models 

    Samaria, Ferdinando Silvestro (University of CambridgeDepartment of EngineeringTrinity College, 1995-02-14)
    This dissertation introduces work on face recognition using a novel technique based on Hidden Markov Models (HMMs). Through the integration of a priori structural knowledge with statistical information, HMMs can be used ...

  • Numerical and experimental modelling of microwave applicators 

    Dibben, David (University of Cambridge, 1995-10-24)
    This thesis presents a time domain finite element method for the solution of microwave heating problems. This is the first time that this particular technique has been applied to microwave heating. It is found that the ...

  • PrologPF: Parallel Logic and Functions on the Delphi Machine 

    Lewis, Ian (University of CambridgeComputer LaboratoryGirton College, 1998-06-16)
    PrologPF is a parallelising compiler targeting a distributed system of general purpose workstations connected by a relatively low performance network. The source language extends standard Prolog with the integration of ...

  • 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 ...

  • Transfer bond stresses generated between FRP tendons and concrete 

    Lees, Janet Marillyn; Burgoyne, Christopher John (Institute of Civil EngineersMagazine of Concrete Research, 1999)
    There is a growing interest in the use of new materials in construction. Materials such as fibre-reinforced plastics (FRPs) are lightweight, strong, and, for the most part, non-corrodible. Hence, the use of FRPs as ...

  • Design of Sandwich Structures 

    Petras, Achilles (University of CambridgeDepartment of Engineering, 1999-05)
    Failure modes for sandwich beams of GFRP laminate skins and Nomex honeycomb core are investigated. Theoretical models using honeycomb mechanics and classical beam theory are described. A failure mode map for loading under ...

  • Embedded discontinuities for softening solids 

    Wells, Garth Nathan; Sluys, LJ (Proceedings of the 4th Asia-Pacific Conference on Computational Mechanics (APCOM '99)Proceedings of the 4th Asia-Pacific Conference on Computational Mechanics (APCOM '99), 1999-12-06)
    Additional, discontinuous functions are added to the displacement field of standard finite elements in order to capture highly localised zones of intense straining. By embedding discontinuities within an element it is ...

  • Discrete analysis of localisation in three-dimensional solids
