A Study of Measuring Intracranial Pressure Using a Non-Invasive Piezoelectric Sensor
… of the human head to measure the integrated hoop strain. Using this hoop strain, the pressure is then calculated from a known coupling factor of strain to pressure outputted from finite element modeling simulations. The coupling factor is then incorporated into a final calibration factor to …

A fabrication stress model for axisymmetric filament wound composite structures
… and fiber stiffness degradation in a compressive strain state. Two case studies were selected to evaluate and to illustrate the use of the fabrication stress model: the space shuttle booster Joint overwrap and a filament wound composite bottle. The analysis results of the overwrap case study show …

Modelling of the filament-winding fabrication process
… performed by comparing experimental pressure and strain data, for the fabrication of a filament wound bottle, with results of an analytical model. The final analytical results using consecutive models of the filament wound bottle show reasonable agreement with experimental pressure and hoop strain …

Using GPS to Quantify Three Dimensional Storage and Aquifer Deformation in the Virgin River Valley, NV
… simulations have shown that horizontal strain is significant. A field based investigation in Mesquite, NV, was undertaken from May to July, 2003, for the purpose of evaluating the significance of horizontal strain during an aquifer test. The hydraulic heads in the aquifer were monitored …

Performance monitoring and numerical modelling of a deep circular excavation
… scheme included distributed fibre optic strain sensing instrumentation and conventional inclinometers in the shaft wall to measure bending and hoop strains, as well as wall deflections during several construction stages. Further inclinometers and extensometers were installed around the …

Novel, low-cost, CFRP pressure vessel design for hydrogen fuel cell applications
… the burst pressure. The stress analysis and strain behaviour of the CFRP tube were modelled using the Classical Lamination Theory. Specimens were made using the same CFRP material as the tube and were tensile tested to give an initial set of approximate properties to be used in the design …

Axial compressive behaviour of FRP-confined high-strength concrete
… specimen slenderness, concrete shrinkage, strain measurement method, FRP overlap and lateral prestress were investigated. The test specimens were manufactured with aramid FRP (AFRP), carbon FRP (CFRP) or high-modulus CFRP (HMCFRP) and their unconfined concrete strengths ranged from 34.0 to …

Mechanical modulation of indirect repair mechanisms for improved hematopoietic recovery
… crowding (MMC) and the mechanical cue of strain can regulate angiogenesis. The addition of synthetic MMC to in vitro cultures replicates the endogenous occupation of fluid space due to macromolecules. We explored how MMC affects the basement membrane formation of VECs, and determined that …
