Multi-level analysis of localisation problems
(2001)
Localisation processes, such as shear banding and necking, have been investigated following a macroscopic and a microscopic approach. Both approaches have been formulated within a finite deformation plasticity framework. ...
Computational modelling of cracks in viscoplastic media
(Proceedings of the 10th International Conference on FractureProceedings of the 10th International Conference on Fracture, 2001)
A newly developed numerical model is used to simulate propagating cracks in a strain softening viscoplastic medium. The model allows the simulation of displacement discontinuities independently of a finite element mesh. ...
Embedded discontinuities for softening solids
(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
(Proceedings of the European Congress on Computational Methods in Applied Sciences and Engineering (ECCOMAS'00)Proceedings of the European Congress on Computational Methods in Applied Sciences and Engineering (ECCOMAS'00), 2000)
A procedure is illustrated for the determination of the normal direction of a discontinuity plane within a solid finite element. Using so-called embedded discontinuities, discrete constitutive models can be applied within ...
Thin-walled composite deployable booms with tape-spring hinges
(University of CambridgeDepartment of EngineeringWolfson College, 2011-07-12)
Deployable structures made from ultra-thin composite materials can
be folded elastically and are able to self-deploy by releasing the
stored strain energy. Their lightness, low cost due to smaller
number of components, ...
Acoustics and manufacture of Caribbean steelpans
(University of CambridgeDepartment of EngineeringWolfson CollegeInstitute for Manufacturing, 2011-03-15)
The Caribbean steelpan is a pitched percussion instrument that originated in Trinidad and Tobago
during the Second World War. Despite several research initiatives to improve the making of this
relatively new instrument, ...
Social network support for data delivery infrastructures
(University of CambridgeFaculty of Computer Science and TechnologyComputer Laboratory, 2011-10-11)
Network infrastructures often need to stage content so that it is accessible to consumers. The standard solution, deploying the content on a centralised server, can be inadequate in several situations.
Our thesis is ...
The role and contribution of the Chief Technology Officer
(University of CambridgeDepartment of EngineeringIfM Centre for Technology ManagementDarwin College, 2011-10-11)
The Role and Contribution of the Chief Technology Officer
The role of the Chief Technology Officer (CTO) came about because of new organisational demands on technology leaders in the 1980s. The initial research objective ...
Software lock elision for x86 machine code
(University of CambridgeFaculty of Computer Science and TechnologyComputer Laboratory, 2011-07-12)
More than a decade after becoming a topic of intense research there is no
transactional memory hardware nor any examples of software transactional memory
use outside the research community. Using software transactional ...
Vibration from underground railways: considering piled foundations and twin tunnels
(University of CambridgeDepartment of Engineering, 2011-02-08)
Accurate predictions of ground-borne vibration levels in the vicinity of an underground railway are greatly sought after in modern urban centers. Yet the complexity involved in simulating the underground environment means ...
