STRUCTURAL GEOMETRICAL TRANSITIONS UNDER DYNAMIC LOADING OF MATERIALS

Microleakage of Endodontic Temporary Restorative Materials under Dynamic Loading

During endodontic treatment, it is important to create a fluid-tight seal in the access cavity in order to prevent marginal leakage and the ingress of oral fluids and microorganisms into the root canal. Nevertheless, temporary filling materials have received less attention than materials used for a permanent and prolonged use. However, they are an essential link in the chain that leads to disin...

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...

Environment Assisted Cracking of Target Structural Materials Under Different Loading Conditions

Geometrical phase transitions

The geometrical approach to phase transitions is illustrated by simulating the hightemperature representation of the Ising model on a square lattice.

Time-resolved x-ray diffraction techniques for bulk polycrystalline materials under dynamic loading.

We have developed two techniques for time-resolved x-ray diffraction from bulk polycrystalline materials during dynamic loading. In the first technique, we synchronize a fast detector with loading of samples at strain rates of ~10(3)-10(4) s(-1) in a compression Kolsky bar (split Hopkinson pressure bar) apparatus to obtain in situ diffraction patterns with exposures as short as 70 ns. This appr...
