Three-dimensional measurements of fatigue crack closure [PDF]
Three dimensional fatigue crack opening profiles in transparent polymer test specimens were determined. The load required to separate crack faces was measured along the crack profile at various positions through the specimens thickness.

Optimal control of the heave motion of marine cable subsea-unit systems [PDF]
, 1995 One of the key problems associated with subsea operations involving tethered subsea units is the motions of support vessels on the ocean surface which can be transmitted to the subsea unit through the cable and increase the tension.

Advanced Engineering Materials, EarlyView.Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

FATIGUE BEHAVIOR OF WELDED STRUCTURES [PDF]
Fiabilitate şi Durabilitate, 2018 Fatigue is a phenomenon consisting of the accumulation of stresses and deformations that cause cracking and sometimes dismantling or even destruction of structures as a consequence of applying variable loads over time as intensity and position ( load ...

Advanced Engineering Materials, EarlyView.This study investigates the tribological response of 60NiTi alloy under dry, water‐lubricated and high‐temperature conditions. The alloy exhibits decreasing wear volume and friction with increasing temperature due to the formation of protective oxide layers. The work clarifies dominant wear mechanisms and demonstrates the suitability of 60NiTi for high‐
