Review and Assessment of Ratcheting Considerations for Design and Analysis
, 2010 This paper presents theoretical, practical, and computational considerations of significance in assessing the strain ratcheting under combined cyclic loads. Different aspects of ratcheting are covered comparing uniaxial versus multiaxial loading.

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT The present study proposes a combined approach of infrared thermography and 3D XFEM numerical models for crack process investigation in mechanical components such as gears. Over the years, fatigue crack analysis based on energy dissipations in the form of heat generated during fatigue tests has been widely reported, although mainly limited to ...

Evaluation of the ratcheting behavior of Cr-Mo steel used in CNG tank
Results in EngineeringCompressed natural gas (CNG) tanks, due to the frequent filling and emptying during their service life, are constantly subjected to fatigue loading on the tank's wall, which causes premature failure.

Fatigue- Ratcheting Interaction Behavior of AISI 4340 Steel [PDF]
, 2015 Ratcheting is known as accumulation of plastic strain during asymmetric cyclic loading of materials under non-zero mean stress. This study intends to investigate the ratcheting behavior in AISI 4340 steel which is mainly used for designing of railway ...

Experimental Study on the Fatigue Behavior of Ti‐6Al‐4 V Bolted Joints Containing Burrs
Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT One‐way assembly accelerates aerospace manufacturing operations but risks leaving drilling burrs within mechanical joints. The detrimental impact of burrs on fatigue strength is widely recognized in the literature, but the mechanisms driving this “knock‐down” remain unclear. This investigation focused on mechanically fastened Ti‐6Al‐4 V single‐

Feedback and Contagion through Distressed Competition
The Journal of Finance, EarlyView.ABSTRACT Firms tend to compete more aggressively when facing financial distress. This intensified competition reduces profit margins, pushing them further into distress and adversely affecting their industry peers. To study such feedback and contagion effects, we incorporate strategic competition in a dynamic model with long‐term defaultable debt ...

Ratcheting Predictive Methods in RCC-MR Code
, 2009 The structures belonging to Gen IV reactors such as Sodium Fast Reactors (SFRs) and High Temperature Gas Reactors (HTGRs) are submitted to high temperatures and high thermal gradients and must be designed against the risk of ratcheting.

Journal of Prosthodontics, EarlyView.Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.
