Biomechanical Comparison of Wire Circlage and Rigid Plate Fixation for Median Sternotomy Closure in Human Cadaver Specimens
… The purpose of this study was to compare the yield load, construct stiffness, ultimate load, displacement at ultimate load, and post-yield behavior of three sternotomy closure methods (Peristernal wires or Sternalock titanium plates) when stressed in each of three directions: lateral …

Seismic Response of Short Period Structures and the Development of a Self-Centering Truss Moment Frame with Energy Dissipating Elements for Improved Performance
… using an elastic-linear hardening model with post-yield stiffness ranging between -10% and +10% of the initial stiffness. This part of the study was done to gain a general understanding of the influence of natural period and post-yield behavior on the collapse performance of structural systems …

Characterizing the Behavior of Magnetorheological Fluids at High Velocities and High Shear Rates
… within these dampers far exceed existing fluid behavior characterization. The aim of the current study is to identify the behavior of the fluid under these extreme operating conditions. Specifically, this study intends to identify the behavior of MR fluid subject to high rates of shear and high …

The role of molecular length scale on the viscoplastic response of amorphous polymer nanofibers in the glassy state
… result in very different physical and mechanical behavior compared to bulk. Of special interest are nanostructures in which the constituent polymer is in its glassy state to provide structural and dimensional stability against surface forces that are particularly strong at the micron and submicron …

The effects of layer deposition angle and layer temperature on the orthotropic mechanical properties of 3D printed PLA parts
… FEM captured the overall experimental tensile behavior of both the 100% infill and 40% linear infill cases.</p>

Mechanics and multi-physics deformation behavior of polymer electrolyte membranes
… microstructural interpretation to the mechanical behavior. The model is then validated for loading conditions which are expected to occur in the fuel cell, specifically, biaxial tension in the membrane plane and constrained swelling. Biaxial characterization is conducted via in-plane tensile …
