Characterization of Concrete Pavement Joint Surfaces
… especially pavements, the ability to transfer shear load across crack/joint and the cracking resistance are important. This research was conducted in order to develop a testing method and roughness parameter that could better predict the shear load transfer across crack/joint. In addition, the …

Combined Compression and Shear Structural Evaluation of Stiffened Panels Fabricated Using Electron Beam Freeform Fabrication
… thick plate. The panels were tested under two load cases in a combined compression-shear load test fixture. One load case tested the panels' responses to a higher compressive load than the shear load. The second load case tested the panels' responses to an equal compressive and shear load. …

Development of a multi-axial load distribution measurement device
… are poor predictors and there is evidence that shear load is at least equally important in ulcer development. Compared to the numerous commercial systems available for plantar pressure distribution measurement, only a few experimental devices exist for shear distribution measurement. These are …

Estimating Lumbar Spinal Loads During a Golf Swing Using an EMG -Assisted Optimization Model Approach
… of this study was to estimate the lumbar spinal loads at L4--L5 level during a golf swing using musculoskeletal modeling techniques. This study also examined the activation patterns of individual lower trunk muscles during a golf swing using surface electromyographic (EMG) techniques. Data were …

Creation and Validation of a Dynamic, EMG-Driven Cervical Spine Model
… but almost all of them were made to study impact loading (whiplash), which makes them unsuitable for studying activities of daily living. A personalized, dynamic, EMG-driven model is very important, because everybody activates their muscles differently, and that different activation will cause …

Global-local Finite Element Fracture Analysis of Curvilinearly Stiffened Panels and Adhesive Joints
… curvilinearly stiffened panels to the combined shear and compression loadings were studied for different stiffeners' height. It was observed that the magnitude of the minimum principal stress in the panel was larger than the magnitudes of the maximum principal and von Mises stresses. It was also …

Finite Element Analysis of an In Vitro Traumatic Joint Loading Model
… impact injury model that incorporated tangential loading was developed in our lab using intact porcine patellae to produce quantifiable degradation similar to that seen in early stage osteoarthritis. We carried out two separate sets of in vitro impact experiments: (1) axial impactions: an impact …

Buckling Analysis of Composite Stiffened Panels and Shells in Aerospace Structure
… may significantly increase the overall buckling load of the resultant stiffened structure. Initially, an extensive literature review was conducted over the past ten years of published work wherein research was conducted on grid stiffened composite structures and stiffened panels, due to their …

A study of some fundamental equations for the deformation of a variable thickness plate
… and they include the effects of transverse shear deformation and normal stress as well as the variation in thickness. These expressions are very much like those used by Essenburg and Naghdi in a paper presented at the Third U.S. National Congress of Applied Mechanics, June, 1958. However, …

Crack Growth Mechanisms under Anti-Plane Shear in Composite Laminates
… composite laminates subjected to anti-plane shear (mode III) loading. For mode III split-beam test methods were proposed, and initial evaluations were conducted. A single test method was selected for further evaluation. Using this test method, it was determined that the apparent mode III …

Force and strain feedback for distributed actuation
… strain sensor and a novel piezoelectric shear load cell. A test article was built, mounted on a cantilever aluminum beam, and tested. Experiments verified the ability to increase pole-zero separation of a structural transfer function by mixing the outputs of displacement and force …

C-Grid as Shear Reinforcement in Concrete Bridge Girders
… This thesis concludes that C-Grid is a viable shear design option and presents the initial recommendations for design methods. These methods provide a basis for the design of C-Grid shear reinforcing that could be used as a starting point for future testing of full scale specimens. This testing …

BEHAVIOUR AND STRENGTH OF PLATE TRUNNIONS SUBJECTED TO SHEAR LOADING
… designs for trunnions to transfer the sling loads to the structure are dependent on the ingenuity of experienced engineers using empirical equations for design checks. Current design specifications for fabricated plate trunnion recommend that the total sling load be transferred directly by …
