Wave Propagation in Stressed Composites
The Journal of the Acoustical Society of America, 1996 The performance of high-temperature composites can be significantly affected by the presence of residual stresses. These stresses arise due to the mismatch of thermal expansion coefficients between matrix and fibers during cooling from fabrication temperature to room temperature.

Propagating Stress Waves During Epithelial Expansion
Physical Review Letters, 2015 Coordinated motion of cell monolayers during epithelial wound healing and tissue morphogenesis involves mechanical stress generation. Here we propose a model for the dynamics of epithelial expansion that couples mechanical deformations in the tissue to contractile activity and polarization in the cells.
