Experimental/theoretical analyses have already been performed on poly(ε-caprolactone) (PCL) loaded with organic-inorganic fillers (PCL/TiO₂ and PCL/ZrO₂) to find a correlation between the results from the small punch test and Young's modulus of the materials. PCL loaded with Ti2 (PCL = 12, TiO₂ = 88 wt %) and Zr2 (PCL = 12, ZrO₂ = 88 wt %) hybrid fillers showed better performances than those ob...

The carbon-supersaturated SKD11 punch was proposed as a green, or, galling-free, long-life and low energy-consuming forging tool of pure titanium β-titanium alloy that works with friction less work hardening without galling. reduction in thickness increased up to 50% investigate the process on contact interface work-hardening behavior. nitrogen-supersaturated utilized reference for this experim...

inspecting the behavior of the rockfill materials is of significant importance in analysis of rockfill dams. since the dimensions of grains in such materials are greater than the conventional sizes suitable for soil mechanics tests, it is necessary to experimentally study them in specific large-scale apparatuses. in this research, the behavior of rockfill materials in two large rockfill dams co...

Abstract A novel in-plane bending test was used to study edge ductility in DP800 as a common advanced high-strength steel the car industry. The utilized digital image correlation technique measure local and average fracture strain values along of specimen. In contrast widely hole expansion capacity test, impact punch friction, contact stress, out-of-plane on is eliminated by removing punch. Als...

Deep drawing is an important process used for producing cups from sheet metal in large quantities. The process parameters and viscosity of fluid is maintained the major role in the hydro forming-deep drawing process. Hydraulic pressure can enhance the capabilities of the basic deep drawing process for making metal cups. Hydraulic pressure contributes positively in several ways to the deep drawi...

large size direct shear tests (i.e.300 x 300mm) were conducted to investigate the interaction between clay reinforced with geogrids embedded in thin layers of sand. test results for the clay, sand, clay-sand, clay-geogrid, sandgeogrid and clay-sand-geogrid are discussed. thin layers of sand including 4, 6, 8, 10, 12 and 14mm were used to increase the interaction between the clay and the geogrid...
