Dynamic Fracture and Fragmentation

1993
The dynamic fracture and fragmentation of a solid body or structure can result from the application of an intense impulsive load. The scale of such events ranges from shaped-charge jet breakup and rock blasting to astro-physical impacts and creation of planetary debris.

Dynamic Fracture and Fragmentation

AIP Conference Proceedings, 2004
Modeling dynamic fracture and fragmentation has many applications ranging from space debris impact to armor penetration. Modeling scales range from microscopic descriptions at the grain level, to mesomechanical models that average the microprocesses over many grains, to standard continuum models, and up to engineering models at the structural scale ...

The Dynamics of Ethnic Fragmentation

The American Journal of Economics and Sociology, 2005
Abstract.  This paper identifies problems associated with the current empirical measurement of ethnic diversity in economic development literature. An expanded index of ethnic diversity is proposed to include variables such as religion and race, and the results are compared to the prevailing index utilized in empirical literature.

Dynamic Composition of Pervasive Process Fragments

2011 IEEE International Conference on Web Services, 2011
A critical aspect for pervasive computing is the possibility to discover and use process knowledge at run time depending on the specific context. This can be achieved by using an underlying service-based application and exploiting its features in terms of dynamic service discovery, selection, and composition.

Fragmentation dynamics of complex molecules and their clusters

AIP Conference Proceedings, 2013
Complex molecular systems such as large molecules or clusters are characterised by a large number of degrees of freedom. Energies well in excess of individual thresholds for fragmentation can be stored for long times and metastable excited states become important. We will concentrate in this paper on the study of the response of such nanoscale systems,

Multicast routing with dynamic packet fragmentation

Proceedings of the 19th ACM Great Lakes symposium on VLSI, 2009
Networks-on-Chip (NoCs) become a critical design factor as chip multiprocessors (CMPs) and systems on a chip (SoCs) scale up with technology. With fundamental benefits of high bandwidth and scalability in on-chip networks, a newly added multicast capability can further enhance the performance by reducing the network load and facilitate coherence ...

Dynamics and fragmentation of thick-shelled microbubbles

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2002
Localized delivery could decrease the systemic side effects of toxic chemotherapy drugs. The unique delivery agents we examine consist of microbubbles with an outer lipid coating, an oil layer, and a perfluorobutane gas core. These structures are 0.5-12 microm in radius at rest.

Mechanisms of dynamic fragmentation: Factors governing fragment size

Mechanics of Materials, 1985
The fragment size produced in the dynamic fragmentation process is the central issue of this study. Theoretical developments based independently on inherent fracture-producing flaw concepts and on energy balance concepts have been reported previously.

Pre-fragmentation dynamics of C60. A molecular dynamics investigation

Chemical Physics Letters, 1994
Abstract We investigate by classical molecular dynamics the pre-fragmentation dynamics of a C 60 molecule, occurring above 4500 K, and calculate the curve of the caloric equation of state. We discuss the solid-to-liquid transition displayed by C 60 just below the disintegration temperature.

Fragmentation dynamics of NO–NO dimer: A quasiclassical dynamics study

Chemical Physics Letters, 2013
Abstract The quasiclassical trajectory method is applied to the vibrational predissociation of the NO( ν )–NO complex. A new ab initio  potential energy surface was used within a reduced dimensionality model. A metastable resonance state of the complex is prepared, for different intramolecular and intermolecular modes.
