Variable amplitude crack growth in railway axles: influence on inspection intervals
, 2009 Railway axles are designed for infinite life, but occasional failures have been and are observed in service. The failures, which are usually due to fatigue crack propagation, are addressed adopting the concept of “damage tolerance” in order to determine ...

Architecture‐Driven Sensor Stability in Weft‐Knitted Engineering Textiles
Advanced Engineering Materials, EarlyView.Textile‐integrated sensor architectures are systematically compared to evaluate their electromechanical behavior under combined mechanical and environmental loading. Pocket‐based integration exhibits stable and reproducible signals, whereas tunnel‐based routing shows higher sensitivity accompanied by increased variability.

, 2009 In this research work, an assessment of hydraulic cylinder housing is presented. First, the in-service loads are measured for the three most fatigue-stressed cylinders of an earth moving machine: boom, arm and bucket cylinders.

Advanced Engineering Materials, EarlyView.This study explores the discrepancies between bulk mechanics and spatial mapping in a tissue‐mimetic hydrogel model. Microplastic particles create localized stiff mechanical microenvironments that are detectable by cellular‐scale nanoindentation but leave bulk properties unchanged as measured by rheology.

Fast Variable Amplitude Cold Gas Thruster
This fast variable amplitude cold gas thruster was invented by Dr. William C. Stone at the National Institute of Standards and Technology (NIST) around 1995.

Fracture and Structural Integrity, 2018 In the present paper, the approach based on the strain energy density (SED) averaged over a structural volume is reformulated to estimate the lifetime of notched components subjected to variable amplitude (VA) uniaxial fatigue loading.

Oxide tribolayer effects on fretting wear of steel under variable displacement amplitude
Results in EngineeringMost of the studies in the literature dealing with fretting have focused on wear mechanisms without considering the formation of oxide layers, whose nature can vary depending on the displacement amplitude and the material pairing.

Advanced Engineering Materials, EarlyView.CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.
