Powers and Practices in Labor Standards Enforcement
Regulation &Governance, EarlyView.ABSTRACT Wage theft remains a pervasive problem internationally and within the United States. In response, worker advocates have sought stronger laws to deter violations and promote compliance. Yet formal authority alone may be insufficient; labor departments often fail to use the full extent of their legal authority to conduct vigorous enforcement ...

Effect of Pre-strain and Pre-corrosion on Ratcheting Behavior of ASTM A668 Class D Steel [PDF]
, 2016 Ratcheting can be considered as one of the serious problems as this phenomenon causes premature failure of structural components. Ratcheting deformation can be regarded as the stress controlled low cycle fatigue (LCF) response of a material which occurs ...

Ratcheting Strain Accumulation Due to Asymmetric Cyclic Loading of Zircaloy-2 at Room Temperature [PDF]
, 2016 Asymmetric stress cycling leads to accumulation of plastic strain which is called as ratcheting strain. The problem is generally associated with nuclear fuel cladding materials used in nuclear power plants and in pressurized pipe lines.

Influence of Dynamic Strain Aging on Ratcheting Deformation Behavior of SA333 Gr-6 Steel
, 2022 SA333 Gr-6 steel is a candidate material for the primary cooling system in nuclear power plants. During service, piping components experience asymmetrical stress or strain cycling, resulting in plastic strain accumulation and a drastic reduction in ...

Ratcheting of Stainless Steel 304 Under Multiaxial Nonproportional Loading
, 2018 Multiaxial ratcheting is often simulated by use of nonlinear kinematic hardening models, while in reality materials show cyclic hardening/softening and additional hardening under nonproportional loading.

Linear matching method for design limits in plasticity [PDF]
, 2010 In this paper a state-of-the-art numerical method is discussed for the evaluation of the shakedown and ratchet limits for an elastic-perfectly plastic body subjected to cyclic thermal and mechanical load history. The limit load or collapse load, i.e. the

Biological Systems as Physical Data Processors: Evolution as a Case of Embodied Computing
BioEssays, Volume 48, Issue 10, October 2026.Embodied biological computing is process through which biological systems gravitate toward attractors in a solution space through a thermodynamically favored process of information capture. Applications in biotechnology, in particular metabolic engineering are numerous.
