Energy Release and Fragmentation of Brittle Aluminum Reactive Material Cases
Propellants, Explosives, Pyrotechnics, 2021AbstractCylindrical reactive material cases produced by the consolidation of an aluminum powder were tested via explosive launch in a closed chamber. One configuration measured the quasistatic overpressure generated by the case and explosive, and two further tests focused on soft‐catch of fragments before and after striking the chamber walls.

Computational studies on fragmentation of brittle materials
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2012We study dynamic fragmentation of metallic structures using the cracking particles method with obscuration zone. The cracking particles method is an efficient meshfree method for modeling dynamic fracture. Fracture is modeled by a set of crack segments. The cracking particles method does not require the representation of the crack topology.

One fragmentation procedure for brittle material cracking
PAMM, 2006AbstractRealistic modeling of 3D fragmentation procedures with minimal incorporation of restrictions to the crack path is still a challenge in modern computational engineering simulations. The presented approach is used to model failure and cracking in concrete structures, applying an explicit finite element integration scheme.

Modeling and Simulation of Dynamic Fragmentation in Brittle Materials
International Journal of Fracture, 1999Fragmentation of brittle materials under high rates of loading is a commonly occurring phenomenon, but quantitative descriptions of the process have been elusive. Several models for dynamic fragmentation have been suggested in the past. In the present paper we consider two such models based on energy balance and compare their predictions of fragment ...

Fragmentation and hazard analysis of brittle materials under far-field blast loading
Advances in Structural Engineering, 2022When subjected to blast loading, brittle building components such as glass and masonry tend to break into fragments that are propelled at hazardous high velocities. There has been copious research on defining the design resistance of structures subjected to extreme dynamic loading, but research that relates the loading characteristics to fragmentation ...

Fractal fragmentation theory for shape effects of quasi-brittle materials in compression
Magazine of Concrete Research, 2002The influence of the slenderness (shape effects) of a specimen in compression and of the friction between it and the loading platens on the dissipated energy density and on the compressive strength (strain-softening response) is theoretically and experimentally analysed.

Modeling the Flow of Fragmented, Brittle Material
1995In prior papers [1,2], we presented a granulated material model called FRAGBED for use in finite element “hydrocodes” applied to penetration of ceramic armors. It is a nonlocal, multiplane plasticity model (see, for example, Batdorf and Budianski [3], Curran et al [4], Bazant et al [5,6]).

Dynamic fragmentation of a two-dimensional brittle material with quenched disorder
Physical Review E, 1997Fragmentation of a two-dimensional brittle material caused by a rapid impact has been analyzed. Computer simulations together with simple arguments are used to obtain a qualitative understanding of crack formation, which is then used to derive an exponential fragment size distribution valid in the large fragment size limit.
