Three popular shear tests—the 10° off-axis, the ±45° tensile and the Iosipescu specimen tested in the modified Wyoming fixture—for shear modulus measurement are evaluated for a graphite-epoxy composite material system. A comparison of the shear stress-strain response for each test method ...
The moduli of elasticity, G for shear and E for tension, are ratios of stress to strain as measured within the proportional limits of the material. Thus the modulus is really a measure of the rigidity for shear of a material or its stiffness in tension and compression. For shear or ...
Young’s modulus \(E_{L} ,E_{R} ,E_{T} \): Longitudinal, Radial and Tangential Young’s modulus for wood specimens \(f_{ij} (\theta ),g_{ij} (\theta )\): Angular functions \(G_{ij} \): Shear modulus of composite material \(K_{\mathrm{I}} ,K_{{\mathrm{II}}} \):...

The effect of various offaxis angles and lamina material properties on the shear modulus and the stress distribution of a circular cut-out in an orthotropic composite plate under shear loadings are presented. Based on the generalized Hooke''s law, the generalized plane stress condition and the ...
It is shown that the critical exponent for the effective shear modulus of a composite medium where a compliant polymer matrix is filled with ferromagnetic particles may significantly depend on the external magnetic field. The physical consequence of this dependence is the critical behavior of the rela...
Values of G12 were found to be approximately proportional to the shear modulus Gm of matrix material but were about 30% lower than predicted by the theory of Hashin and Rosen. The anisotropy of the carbon filaments and voids in the composite samples were proposed to account for the ...
and inhibition of non-muscle myosin II motors, respectively. TheGshowed a larger intra- than inter-cellular variability and it was mostly determined by the cytosol. Our shear modulus microscopy can thus map the spatial distribution ofGof soft materials including gels, cells and tissues while allowi...
When dealing with combinations of materials, it is better to deal with modulus weighted section properties (EA, EI, GJ) rather then simple area section properties (A, I, J). Assuming the outer shell is perfectly bonded to the inner foam, the stiffnesses of each will add to get the total...
