Fluids are pervasive in the Earth’s crust and saturate fractures faults. The combination of fluids gouge layers developing along faults can generate different viscosities. Such viscous were found to influence reactivation, frictional stability faults, eventually dynamics propagating earthquake ruptures. We reproduced laboratory earthquakes on analog material (PMMA) study lubricant fault stabili...

The objective of this study was to analyze the effect cement thickness on strain and stresses resulting from polymerization resin using photoelasticity Finite Element Analysis (FEA). For study, twenty upper first premolars with inlay cavity preparation were constructed photoelastic restored composite inlay. samples divided into two groups (n = 10) according film material. Group 1, 100 ?m; for 2...

Phase-stepped photoelasticity is a powerful method for full-field stress analysis, but sequential collection of the multiple required images limits the technique to static loading applications. We have developed a system that utilizes diffraction gratings to collect four phase-stepped images simultaneously with a single camera for transient loading applications. Two adjacent, perpendicularly or...
