Effects of Thickness and Indenter Tip Geometry in Nanoindentation of Nickel Films
… mechanical properties of thin films on substrates and bulk materials, and the effect of geometrically different indenters (Berkovich, cubecorner, and conical). X-ray diffraction (XRD), transmission electron microscope (TEM), scanning electron microscopy (SEM), and atomic force microscopy …

Micromechanics of ultra-high molecular weight polyethylene fibre composites
… punches. It is shown that the punch penetrates the composites without fibre fracture but by the formation of mode-I cracks along the fibre directions. The results indicate that the high penetration resistance of the composites by sharp-tipped punches is attributed to the high toughnesses …

Temperature dependent dynamic response of open-cell polyurethane foams
… pads. These experiments were conducted under strain rates of 10$^2$ s$^{-1}$ and under temperature conditions ranging from -20 to 40\textdegree{C}. This temperature range was chosen to simulate desert and arctic conditions, with a strain rate regime chosen to represent loads that would occur …

Analisi teorica, numerica e sperimentale dei processi di grandi deformazioni nei materiali duttili
… bandind, cinematic and isotropic hardening.,strain rate dependency, thermal effects, the loosing of the original mechanical properties, are just a part of a bigger list of factors that affect the deformation properties of a body, leading to many complications in the theoretical analysis of …
