The six independent elastic constants of Sr2RuO4 were determined using resonant ultrasound spectroscopy on a high-quality single-crystal specimen. The constants are in excellent agreement with those obtained from pulse-echo experiments performed on a sample cut from the same ingot. A calculation of the Debye temperature using the measured constants agrees well with values obtained from both spe...
Numerical models commonly account for elastic inhomogeneity in cortical bone using power-law scaling relationships with various measures of tissue density, but limited experimental data exists for anatomic variation in elastic anisotropy. A recent study revealed anatomic variation in the magnitude and anisotropy of elastic constants along the entire femoral diaphysis of a single human femur (Es...
We performed simultaneous high-fidelity left ventricular pressure and echocardiographic dimension measurements in 30 patients with normal left ventricular function (group 1; n = 6), moderate-tosevere aortic regurgitation (group 2; n = 14) or congestive cardiomyopathy (group 3; n = 10). We determined diastolic stress, strain and strain rate in all 30 patients and fitted the data to a simple elas...
A phenomenological lattice dynamics model based on the bond-charge model has been developed that describes how strain affects phonon frequencies and elastic constants in groups IV ~homopolar! and III-V ~heteropolar! semiconductor thin films and strained layers. A quasiharmonic approach is adopted, using force constants that depend linearly on strain. This model uses available experimental data ...
