Methodology to Validate Traffic Speed Deflection Devices (TSDDs) Measurements Using Laser Doppler Vibrometers (LDV) Sensors
… pavement management and design. Traffic Speed Deflection Devices (TSDDs) provide an efficient way to collect pavement structural condition data at the network-level. However, the integration of TSDD measurements into pavement management and design applications remains limited due to the lack of …

Use of the Traffic Speed Deflectometer for Concrete and Composite Pavement Structural Health Assessment: A Big-Data-Based Approach Towards Concrete and Composite Pavement Management and Rehabilitation
… collected in a non-destructive manner such as a deflection testing device. This more holistic approach was proven to be more cost-effective than the current state of the art, in which the pavement manager grounds their maintenance and rehabilitation-related decision making on surface distress …

Investigation of Zinc Oxide Nanowires for Impedance Based Structural Health Monitoring
… into a carbon fiber epoxy composite. The beam deflection velocity was measured as a varying voltage was applied to the composite. Using Hamilton's Principle and Galerkin's method of weighted residuals, a mathematical model was derived to estimate piezoelectric constants for the composites from …

Numerical modelling of the aluminium extrusion process and comparison with results obtained from industrially extruded complex sections.
… which are likely to be affected are load, deflection, velocity and temperature. The results indicated that the design of the die affected the process parameters. The microstructure evolution during the extrusion process was investigated for the selected complex geometries. The following …

Development of a Finite Element Based Injury Metric for Pulmonary Contusion
… values of medial-lateral chest compression and deflection velocity of 25.3 ± 2.6 % and 4.6 ± 0.42 m·s-1 respectively. These data provided quantified loading conditions associated with crash-induced PC and a framework for the remaining research studies, which were focused on blunt impact …
