چکیده

Closed-cell cellular materials gained tremendous interest in their application aerospace, shipbuilding and defence industries due to exceptional impact energy absorption lightweight characteristics. To assess the suitability of these practical utilisation, a proper characterisation dynamic loading is necessary. This paper investigates closed-cell aluminium foam's deformation behaviour low-velocity projectile experimentation finite element analysis. The collapse mechanism was numerically empirically examined. experiment analysis were found be good agreement. tests conducted using an instrumented drop-tower with several tips 105 J. Finite Element modelling ABAQUS explicit undertaken. results reveal that FE true foam properties solid geometry has correlation experimental results. In this study, four impactors/indenters (flat-faced, hemispheric, conical, truncated-conical) used. A detailed structural during been explored XCT data tools.

Cusp Shapes under Cone Deformation

A horospherical torus about a cusp of a hyperbolic manifold inherits a Euclidean similarity structure, called a cusp shape. We bound the change in cusp shape when the hyperbolic structure of the manifold is deformed via cone deformation preserving the cusp. The bounds are in terms of the change in structure in a neighborhood of the singular locus alone. We then apply this result to provide info...

Cell fasting: Cellular response and application of serum starvation

  Humans suffer transient or persistent starvation due to a lack of food intake, either because of fasting, voluntary dieting, or due to the scarcity of available food. At the cellular level it is possible to possess pathological starvation during ischemia and solid tumors. Blood provides many nutrients to our cells, and researchers provide these nutrients to cells in culture in the form of en...

Cell Deformation Modeling Under External Force Using Artificial Neural Network

Embryogenesis, regeneration and cell differentiation in microbiological entities are influenced by mechanical forces. Therefore, development of mechanical properties of these materials is important. Neural network technique is a useful method which can be used to obtain cell deformation by the means of force-geometric deformation data or vice versa. Prior to insertion in the needle injection pr...

evaluation of mechanical behaviour of sandstone and andesibasalt rockfill materials using triaxial & direct shear tests

the mechanical behaviour of rockfill materials and aggregates depends not only on particle size and compaction, but also on their strength and lithological properties. in this research two types of large triaxial and direct shear tests are performed on rockfill materials. this paper compares the stress-strain behaviour of sandstone and andesibasalt materials in triaxial compression tests (3006...
