Variation in the dispersion of axisymmetric waves in infinite circular rods with crystallographic wire texture

摘要: This paper presents the solution to frequency equation for a number of polycrystalline, textured circular rods having transverse isotropy. The effective, second-order elastic stiffness tensors were estimated using recursive general Hill arithmetic mean (GHAM). velocity dispersion curves combinations materials and crystallographic fiber or wire textures calculated variation due texture displayed. At large wavelengths, exhibits lowest-order axisymmetric mode which varies only with directional Poisson’s ratios in manner similar that isotropic aggregates. In this wavelength regime, waves propagate nondispersively at wave speed, C0, as dictated by Young’s modulus. wavelengths smaller than rod radius, more influenced full anisotropy textures. these anisotropic deviated ...
