Where μ is the shear modulus of the unstressed rock (with an isotropic distribution of cracks), Pc is a characteristic crack closing pressure, σ0 is normal stress, and B=BN/BT is the ratio of normal to tangential compliances of individual cracks. ...
Measurement of residual stress and elastic modulus of polycrystalline 3C-SiC films deposited by low-pressure chemical vapor deposition Residual stress and in-plane biaxial modulus of polycrystalline 3C-silicon carbide (poly-SiC) films are studied using bulk and surface micromachined micros......
The shear modulus of pulp fibers is difficult to measure and only very little literature is available on this topic. In this work we are introducing a method to measure this fiber property utilizing a custom built instrument. From the geometry of the fiber cross section, the fiber twisting ang...
The behavior of the effective shear modulus G ef and internal friction in Si is comprehensively studied in the temperature range in which an anomalous hysteresis G ef ( T ) exists. It is shown that this hysteresis is caused by mobile dislocations and that the pinning of these dislocations by...
The dynamic oscillatory shear test is generally conducted within the region of linear viscoelastic response (LVE). This test is performed to measure the complex shear modulus (G*) and phase angle (δ) which mutually describe the viscoelastic response of bituminous materials. A rheometer under the ...
Young’s modulus of blank calcium alginate is reported to be in the range of 0.5–5.0 N/mm2 [16]. With the increase in the capsules content in the sand, a greater number of interactions between the sand grains and capsules were expected. The interaction with the low-stiffness particles of...
Young's modulus, shear modulus, and Poisson's ratio are defined in general and values tabulated for some of the more important directions in the crystal. Graphs of these moduli are also plotted as a function of crystal direction for orientations in the (100) and (110) planes as well as ...
the tip itself, which is intended to absorb impulsive energy for the buffer effect, would pose a negative influence on the accurate height measurement, microgrids made of silicon material (Young’s modulus: ~190 GPa) with a nominal step height of ~113 nm were first used for calibration....
where G13c is the principal (longitudinal-transverse) shear modulus of the composites, and subscripts 1 and 3 refer to fiber direction and transverse direction, respectively (Fig. 9-1). The maximum shear strength in the matrix is (9-8)τmax=GmΔus Consequently, (9-9)τmax=ILSS⋅GmG13...
