Cumulative Damage: Cell Death in Posthemorrhagic Hydrocephalus of Prematurity [PDF]
Cells, 2021 Globally, approximately 11% of all infants are born preterm, prior to 37 weeks’ gestation. In these high-risk neonates, encephalopathy of prematurity (EoP) is a major cause of both morbidity and mortality, especially for neonates who are born very ...

Fatigue damage assessment of bogie frame based on an improved nonlinear cumulative damage model [PDF]
Scientific ReportsThe structural damage of rail vehicle bogie frames is mostly caused by fatigue cumulative damage under the action of multi-level complex loads. Under complex loads, the sequence effect and coupling effect between loads have a significant impact on ...

A New Cumulative Fatigue Damage Rule Based on Dynamic Residual S-N Curve and Material Memory Concept
Metals, 2018 This paper introduces a new phenomenological cumulative damage rule to predict damage and fatigue life under variable amplitude loading. The rule combines a residual S-N curve approach and a material memory concept to describe the damage accumulation ...

Fatigue Life Assessment of Intercity Track Viaduct Based on Vehicle–Bridge Coupled System
Mathematics, 2022 During the long-term operation of an urban railway viaduct, it is subjected to multiple cyclic loads caused by the movement of a vehicle. As a result, the fatigue life of the bridge should be fully considered during the design process.

Maintenance Overtime Policy with Cumulative Damage [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2018 We propose an extended maintenance overtime policy for the cumulative damage model where an operating unit suffers some damage due to shocks. It is assumed that the total damage is additive, and the unit fails when the total damage has exceeded a ...

Process Condition Diagram Predicting Onset of Microdefects and Fracture in Cold Bar Drawing
Metals, 2021 This paper presents a process condition diagram (PCD) that not only identifies conditions under which materials fracture during bar drawing, but also infers the presence or absence of microdefects such as microvoids and microcracks in the drawn material ...
