Stress singularity of a notch in a higher-order elastic solid under anti-plane deformation
Published 2020“…Specifically, for a given notch angle the stress exponent becomes more negative with decrease in the first Lamé constant λ and the third-order elastic constant n, and with the increase in the magnitude of the negative third-order constant m, while it varies non-monotonically with the second Lamé constant (shear modulus) µ.These results have significant implications for notch-like defects in soft solids, e.g., replacement tissues, industrial robots and devices in biomedical applications.…”

Seismic behavior of interior concretebeam-column joints with non-seismic and limited seismic detailing
Published 2009“…Recent post-earthquake investigations indicated that extensive damage occurred as a result of excessive shear deformation and severe strength degradation of the beamcolumn joints in non-seismically detailed frames, thus leading to full collapse of structures. …”

Study of endothelial cell apoptosis using fluorescence resonance energy transfer (FRET) biosensor cell line with hemodynamic microfluidic chip system
Published 2014“…A 12% apoptotic rate (nearly a 4-fold increase compared to the static condition) was observed when the endothelial cells were exposed to a high glucose concentration of 20 mM under 2 h exhaustive pulsatile shear stress of 30 dyne cm−2 and followed with another 10 h normal pulsatile shear stress of 15 dyne cm−2. …”

Critical temperatures in thermocompression gold stud bonding
Published 2012“…Under similar bonding conditions, the critical temperature is lower for a harder substrate than for a softer substrate, primarily because of larger interfacial shear stresses. This is supported by the observation on the interfacial shear stress distribution at the bonding interface based on finite element simulation models of substrates with different hardness.…”
