Modeling dynamic fragmentation of heterogeneous brittle materials

International Journal of Impact Engineering, 2017
Abstract Extreme high-rate loading of structural materials triggers a complex process of fragmentation involving probabilistic, energetic and mechanical aspects. One-dimensional modeling approaches based on elastodynamics have been successfully used to predict strain-rate dependence of average fragment-size. However, the ability of such approaches to

Dimensional effects in dynamic fragmentation of brittle materials

Physical Review E, 2005
It has been shown previously that dynamic fragmentation of brittle D -dimensional objects in a D -dimensional space gives rise to a power-law contribution to the fragment-size distribution with a universal scaling exponent 2-1/D . We demonstrate that in fragmentation of two-dimensional brittle objects in three-dimensional space, an additional ...

Continuum modelling of dynamic behaviour and fragmentation of quasi-brittle materials: application to rock fragmentation by blasting

International Journal for Numerical and Analytical Methods in Geomechanics, 2005
Summary: Fragmentation plays an important role in a wide variety of industrial processes such as blasting, demolition, crushing, cutting, etc., in which one desires to cause fragmentation in the most efficient and controlled manner. Nevertheless, a consistent theoretical description of this process is not yet available.

Fragmentation of brittle materials at high rates of loading

Journal of Materials Science, 1991
Experiments involving the fragmentation of SiC during both quasistatic and high-rate compressive loading are described. Measured fragment size distributions are considered in terms of current ideas regarding high strain rate damage and microfracture.
