Quasistatic and Dynamic Regimes of Granular Material Deformation under Impulse Loading

A two-dimensional computer code, using a multi-material Eulerian finite element formulation, was used to investigate the dynamic micromechanical behavior of granular material. The main results are : The strain-rate insensitive material model provides the correct increase in the dissipated energy with an increase of shock pressure ; An increase in the initial porosity or the pressure results in ...

Large Deformation of Nitinol Under Shear Dominant Loading

Full-field quantitative strain maps of phase transformation and plasticity in Nitinol under large sheardominated deformation are presented. To achieve a sheardominated deformation mode with relatively uniform stresses and strains, a shear compression specimen (SCS) geometry was utilized. Shear deformation appears to impede the development of the strain localization during phase transformation t...

Analysis of Five Parameter Viscoelastic Model Under Dynamic Loading

The purpose of this paper is to analysis the viscoelastic models under dynamic loading. A five-parameter model is chosen for study exhibits elastic, viscous, and retarded elastic response to shearing stress. The viscoelastic specimen is chosen which closely approximates the actual behavior of a polymer. The module of elasticity and viscosity coefficients are assumed to be space dependent i.e. f...

Microleakage and fracture patterns of teeth restored with different posts under dynamic loading.

STATEMENT OF PROBLEM Many studies concerned with the microleakage of endodontically treated teeth restored with posts and cores and subjected to loading can be found in the literature. However, no studies have investigated microleakage under dynamic loading with simultaneous dye penetration, which is more relevant to clinical situations. PURPOSE The purpose of this study was to compare microl...

Pattern formation and selection in quasistatic fracture.

Fracture in quasistatically driven systems is studied by means of a discrete spring-block model. Developed from close comparison with desiccation experiments, it describes crack formation induced by friction on a substrate. The model produces cellular, hierarchical patterns of cracks, characterized by a mean fragment size linear in the layer thickness, in agreement with experiments. The selecti...
