The Young's modulus, bending strength, apparent density, and ash content of 155 human compact bone bending specimens were determined. Both Young's modulus (E) and bending strength (S) were strongly correlated to tissue dry apparent density (rho a). Based upon the correlation coefficient (R) ...
The results show that the Young's modulus of two species at the elevated water content and temperatures was largely affected by the water content over 5% and the heating temperatures 80掳C or higher. The bending strength at normal temperature or higher was highly dependent on the water...
The tensile strength and Young's modulus of Johns‐Manville experimental drawn glass fibers were measured by a bending method which consists of twisting a loop in a fiber and pulling the ends until the loop breaks. The tensile strength observed by this method was two to three times higher than...

The premise of this work is that the bending response of honeycomb specimens may be significantly different from that of solid specimens, and therefore it is necessary to establish a sound protocol for the determination of the axial Young's modulus of honeycomb specimens under bending. Toward this...

The consistent stiffness of the test machine including the jig was obtained by using a dummy specimen. For the test of the bulk, increasing repeated load within a level less than the fracture load was applied to stabilize the loading condition. The Young’s modulus calculated by using the ...
The thickness is about 2–5 µm for the film and 1 mm for the substrate.Young's moduli of the films are obtained by a new three points bending apparatus. Young's modulus of coating depends both on silica content and on the nature of the silica used as a filler....
