Membrane deflection in inline drip emitters
… the force exerted by the membrane at a given deflection. The results were compared to analytical models of the deflection of a simply-supported or clamped rectangular plate with a point load, and it was found that these models do not accurately describe the measured behavior. A sensitivity …

Large-deflection analysis of cord composite plates
Cord composites, which are constructed by embedding cords in a rubber matrix, have been used in industry for many years. This type of composite is strong in extension in the cord direction but very flexible with regard to bending. Previous studies in predicting the elastic constants of wire cord …

Asteroid deflection campaign design integrating epistemic uncertainty
… an excellent opportunity to demonstrate asteroid deflection techniques. However, applying a deflection technique to a hazardous asteroid in real-world situations requires extreme care for decision makers due to inherent uncertainty. The forms of uncertainty can be epistemic or aleatoric. Epistemic …

Slope deflection analysis of trussed rigid frames
… three dimensional truss-rigid-frame with elope deflection method is investigated in this thesis. In the first few chapters of this thesis the elope deflection equations for solving the trussed-rigid-frame problem were derived. The point of great importance in deriving slope deflection equations …

Deflection comparisons of different wooden floor systems
Full-scale structural deflection tests were conducted on floor sections with 2"x4" , 2"x6", and 2"x8" joists at four different stages of construction. Stage A was joist alone; stage B joists plus 1/2" plywood subflooring; stage C, stage B plus 25/32" oak strip flooring laid parallel to the joists; …

Prediction of deflection of helical anchors under load
… requires proper modeling of axial load-deflection characteristics. To keep pace with advances in structural analysis, there is much need for more practical and scientific work on the load-deflection prediction of deep foundations including Helical Anchors.</p> <p>The load-settlement …

Asteroid hazard mitigation: deflection models and mission analysis
… to construct a set of Pareto-optimal asteroid deflection missions. The Pareto-optimality is here achieved not only by maximizing the deflection of the threatening object, but also by minimizing the total mass of the deflection mission at launch and the warning time required to deflect the …

Comparing the deflection of different colored glass strips
… black, transparent blue, and white glass. The deflection of the center point of each strip of glass was measured as the temperature was held constant. A proportional relationship of deflection with time was found for the red and white glass and the deflection of the clear, black, and blue glass …

Strain-deflection relationships of freely vibrating wood beams
… be able to determine the vibration amplitude (or deflection) from strain vibration data. The objectives of this project were to theoretically and experimentally determine the relationship between midspan flexural strain and midspan deflection of freely vibrating wood beams with various end …

Small and large deflection of clamped skew sandwich plates.
The problem of the small and large deflection behaviour of skew sandwich plates with built-in edges and subjected to a uniformly distributed load is investigated. Non-linear partial differential equations governing the load-displacement relationship for such plates are derived using the principle …

Wing Deflection Analysis of 3D Printed Wind Tunnel Models
… difference in wake distribution and wingtip deflection for multiple configurations.</p> <p>Numerical simulation data taken in the form of CFD and FEA was used to validate data taken in the wind tunnel experiments. The experiment utilized a wake rake to measure 3 different spanwise locations …

The load/deflection behavior of pretensioned cable/pulley transmission mechanisms
… mechanism. In this thesis we model load/deflection behavior of one particular transmission option; closed circuit cable/pulley transmissions. Cable drives are well suited to force and position control applications because of their unique combination of zero backlash motion, high stiffness …

Surface hardness classification via unmanned aerial vehicles gripper finger deflection
<p>The purpose of this thesis is to ascertain the feasibility of using strain gauges attached to a Unmanned Aerial Vehicle (UAV) gripper to determine, upon impact, the hardness of a landing site. We design and fabricate a four finger gripper that uses a rotary component to convert the rotational …

Evaluation of FWD software and deflection basin for airport pavements
… by statistical analysis using three sets of FWD deflection data produced by three loads with magnitudes of 9, 12, and 16 kip at an identical location of an airport pavement. It is shown that EVERCALC software produces more consistent and accurate modulus values than the BAKFAA and MODULUS …
