..., and interstitial bone. Based on close experimental observations, a Monte Carlo algorithm is implemented to build the natural bone composite microstructure. To represent the hierarchical nature of bone, the algorithm incorporates macroscopic morphological components, such as its porosity and osteonal volume...

...Eitan Hirsch; Meir Mayseless Jets that emanate from high density porous liners are most widely used for penetration into Earth materials. These shaped-charges differ from those that contain solid copper liners in three major aspects: the porosity, the usually higher initial density, and the very...

... existing solutions are only applicable to single-porosity and single-permeability models, which could fall short when the porous material exhibits multiporosity and/or multipermeability characteristics, such as secondary porosity or fracture. This paper extends the plane strain and axisymmetric Mandel-type...

... θ = − 3 2 p r 0 ( 1 ρ 2 + 1 ρ 4 ) X ϕ = − 3 2 p r 0 ( 1 ρ 2 + 1 ρ 4 ) Since this artificial body force is highly concentrated near each cavity, the work-rate contribution for dilute porosity stays...

... compaction waves having a dispersed two-wave structure are predicted for mild impact of dense HMX (porosity ∼ 19 % ), and steady supersonic compaction waves having a discontinuous solid shock followed by a thin compaction zone are predicted for stronger impact. Short duration hot spots having peak...

... size 35 microns were used to make pellets of 35% porosity and 70% liquid saturation. As the capillary number increased, the failure mode changed from brittle cracking to ductile plastic flow. This change coincided with the transition from strain-rate independent flow stress to strain-rate dependent...
