Closed-form solutions for simplified fretting wear profiles prediction incorporating an inverse identification of local wear rates

This paper proposes a method for estimating the local wear rates operating within a flat-on-flat contact subjected to fretting wear through an inverse identification approach. Using an error minimization strategy involving a limited number of…

Scenario for the formation of fretting obtained TTS in TA6V from detailed microstructural analysis

Fretting is defined as surface degradation caused by small oscillatory movements. Fretting in the gross slip regime produces high local stresses at the surface. This results in wear and subsurface plastic deformation, which can create a nanosized…

The Effect of Natural Convection on Thermal Explosion in Open Storage Silo

Abstract In cylindrical storage silos, exothermic reactions carry the inherent danger of triggering a thermal explosion. Such an explosion can transpire when the rate at which heat is generated by the chemical reaction exceeds the heat dissipated…
