This paper presents an extensive laboratory testing program undertaken to study the influence of interface bonding and particle size, roughness, and shape on the Young's modulus of ice-saturated frozen sand in triaxial compression. The program also included the influence of particle stiffness...

... to the silicon substrate at one end. Test systems incorporating force, strain, and displacement measurement are used, and Young's modulus can be obtained by three methods, which yield equivalent results. Tensile stress-strain curves of polysilicon have been recorded over the temperature range 30 to 250°C...

However, the silicon did indicate a slight decrease in Young's modulus. CVD diamond polycrystalline silicon radiation effects nanoindention Raman Spectroscopy MEMS...

..., the wedge-action grip was found to cause greater measurement variability, especially in Young's modulus. The analysis of system compliance, on the other hand, reinforced the statements in both testing standards that an accurate strain and modulus measurement would require the use of extensometer...

..., Young's modulus is very sensitive to phase transitions and polarization level. In the present report, the Young's modulus E ( T ) and the mechanical loss Q -1 ( T ) are measured in order to study phase transitions and temperature-induced depolarization. The temperature range is 100 K to 700 K. Two...
