Many mechanical properties of glasses and liquids, such as the large shear susceptibility compared to the compressibility, seem strange and unexpected. However, they are basically the same as those found for irradiated crystals at low defect concentr

A non-contact EMAT technique of ultrasonic generation and detection was used to make high temperature measurements of the C44 deviation from perfect crystal behavior just below the melting temperature and a much smaller effect for C′, which is to b

The mechanical response of amorphous materials to shear stress is analogous to the dielectric or magnetic response to an electric or magnetic field. The spectrum consists of a resonance and a relaxation. The resonance is at high frequency, typically

We have calculated the transition rate for a string through a pinning point potential barrier. The result for this N-dimensional system has the one-dimensional form τ -1 = ν eff exp (-ΔU/kT eff ), where ν eff is an effective frequency, ΔU the ba

We have measured the shear modulus and its temperature dependence of Pd40Ni40P20 using an EMAT technique. Measurements were made of the temperature dependence at constant heating rate of the infinite frequency shear modulus G. Values of the shear sof

We have calculated the transition rate for a string unpinning from a point barrier, using a truncated parabolic potential. In this approximation, it was shown that the result for this N-dimensional system has the one-dimensional form R=νeffexp (−

We find convincing evidence of dislocation tunneling in the superconducting state of an aluminum crystal below 1 K, that is, a flattening of the temperature dependence of applied stress amplitude between 0.1 - 0.5 K for constant decrement of amplitud

A recently given interstitialcy model for simple condensed matter states is tested by comparing predicitions of the model with available evidence for (1) the structure as given by the radial distribution function, (2) the dynamics of glasses found fo
