Performance of Sheet Pile Walls with Rubber-Modified Backfill

This study investigates the behavior of clean sand and sand-rubber mixtures used as backfill materials behind sheet pile walls under vertical loads. Physical model experiments were conducted to assess lateral displacement and pressure for backfills…

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…

High-cycle fatigue behaviors of twinning-induced plasticity steels fabricated by laser powder bed fusion

Twinning-induced plasticity (TWIP) steels fabricated by laser powder bed fusion (LPBF) were subjected to heat treatments at 400°C for 1 h and 800°C for 30 min, followed by high-cycle fatigue (HCF) testing. The results reveal that, despite the high…
