Lattice strain measurements using synchrotron diffraction to calibrate a micromechanical modeling in a ferrite–cementite steel [PDF]
, 2013 In situ tensile tests were performed at room temperature on a ferrite–cementite steel specifically designed for this study. The evolution of the average stress in ferrite during loading was analyzed by X-ray diffraction.Lattice strain measurements were ...

BAUSCHINGER EFFECT DURING SHOCK LOADING [PDF]
, 1992 Parallel shock recovery and wave profile experiments have been performed that exhibit a Bauschinger effect in Si-bronze shocked to 10 GPa. The unloading wave profile in Si-bronze exhibited a quasi- elastic release that had greater departure from the ideal elastic- plastic response than the pure copper samples.

The influence of material anisotropy and spiral welding on tensile strain capacity of spiral welded pipes [PDF]
, 2015 The longitudinal strain capacity of spiral welded pipelines displays to some extents unexplained behaviour. Therefore, they are not (yet) used extensively in offshore applications and harsh conditions, demanding a strain based design. An important factor

Change of the yield stress in roll formed ERW pipes considering the Bauschinger effect [PDF]
, 2017 ERW pipes formed with the roll forming process show a yield stress distribution along the circumferential direction and their quality is strongly influenced by the magnitude and by the distributions of the yield stress.

Investigation of Bauschinger effect in thermo-plastic polymers for biodegradable stents
Current Directions in Biomedical Engineering, 2017 The Bauschinger effect is a phenomenon metals show as a result of plastic deformation. After a primary plastic deformation the yield strength in the opposite loading direction decreases.

Bauschinger effect in uranium. [Rarefaction waves] [PDF]
, 1976 The Bauschinger effect (different elastic-plastic behavior upon unloading) was measured in uranium and a model of the effect developed for use in one-dimensional hydrodynamic codes. Results from plate-impact tests show that rarefaction waves in uranium can be calculated more accurately with this model.

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges
Structural Concrete, EarlyView.Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule
