A test platform for measuring the energy efficiency of AC induction motors under various loading conditions and control schemes/
… of an AC induction motor under steady-state and cyclical loading conditions while operating in both a constant speed mode and while performing speed to speed transitions. The details of the construction are provided. The motor under test is fully characterized and modeled in order to establish …

Incorporating Mullins Effect into the Modeling of Hyperelastic Actuators
… inclusion would help realize their potential in cyclical loading scenarios. One such irreversible framework is the Mullins effect, which describes a range of phenomena, most importantly stress softening, that all depend on the hysteresis in deformation of the material. This thesis proposes a …

Development and preliminary numerical investigations of a dislocation density-based finite-strain rate-dependent elastoplasticity constitutive model
… strain compression, uniaxial compression, and cyclical loading. The model is fit to 5XXX series aluminium mechanical test data sourced from literature, and from preliminary investigations, it is shown that the work hardening behaviour and associated dislocation density evolution under the given …

Normal-strength and high-strength concrete columns under cyclic axial load and biaxial moment
… The lateral load was applied monotonically and cyclically. To predict the behavior of concrete columns under monotonic and cyclic compressive loadings, a computer code was developed to produce the moment-curvature diagram for concrete sections. The moment-curvature diagram was then input in …

The Investigation of Transverse Joints and Grouts on Full Depth Concrete Bridge Deck Panels
… joints were designed and tested in cyclical loading. Each joint was tested on a full scale two girder setup in negative bending with a simulated HS-20 vehicle. The blockouts were built as hollow concrete rings filled with grout and left to shrink under ambient conditions. Thirteen …

Mechanical and biological augmentation of allograft and synthetic graft in impaction bone grafting
… mechanical stability of the prosthesis under cyclical loading,<br/>demonstrated by a reduction in stem subsidence.<br/><br/>Conclusions:<br/><br/>• HBMSC when combined with either allograft or synthetic graft (PDLLA) can<br/>survive the forces of a standard IBG and under osteogenic conditions, …
