Lam This study evaluates energy and carbon use by two types of facilities—conventional confinement and hoop barn-based—within farrow-to-finish pig production systems scaled to produce 5200 and 15,600 market pigs annually i...

In this work, the fatigue behaviour of 316 stainless steel is studied with different critical plane models. Seven cylindrical samples were used for study, being subjected to complex loading paths, generating combined stresses along axial and transversal sample directions, these being: individual stress, hoop alternating a proportional combination non-proportional L-shaped square-shaped stress. ...

During the charging and discharging process of a lithium-ion power battery, intercalation deintercalation can cause volume change in jellyroll internal stress batteries as well, which may lead to battery failures safety issues. A mathematical model based on plane strain hypothesis was established predict stresses both radial hoop directions, with each winding layer obtained. Displacements steel...

Oil and gas pipelines are pressure vessels with steel walls operating at up to 70% of their yield strength. They need to be inspected rigorously to avoid failure and for environmental safety reasons. Magnetic flux leakage (MFL) is the most cost effective technique for in-service corrosion inspection ofburied gas pipelines [1]. In this method, the pipe wall is magnetized to near-saturation using...

Missing pellet surface (MPS) defects are local geometric defects in nuclear fuel pellets that result from pellet mishandling or manufacturing. The presence of MPS defects can cause clad stress concentrations that are substantial enough to produce through-wall cladding failure for certain combinations of fuel burnup, and reactor power level or power change. Consequently, the impact of potential ...

The accurate prediction of reference points on the axial stress–axial strain relationship fiber-reinforced polymer (FRP)-confined concrete is vital to pre-design structures made with this system. This study uses an artificial neural network (ANN) for predicting hoop rupture (εh,rup) and transition zone, namely (εc1) stress (f’c1), stress–strain curves FRP-confined concrete. These are key parame...
