Cyclic Creep Behavior and Modified Life Prediction of Bainite 2.25Cr-1Mo Steel at 455 °C

Metals, 2020
Uniaxial static and cyclic creep tests were carried out on bainite 2.25Cr-1Mo steel at 455 °C. Effects of the unloading rate from 0.6 to 39 MPa/s and valley stress duration from 0 to 30 min on the cyclic creep deformation behavior were discussed.

Assessing energy balance via seismic and mechanical observations in high temperature induced crack damage in marbles

Heliyon, 2023
Assessing the rock physical and mechanical behavior under different temperatures has become of utmost importance. It is well known that thermal stresses induce significant crack damage in rocks due to thermal expansion or phase transformation and volume ...

Isolating the Role of Bone Lacunar Morphology on Static and Fatigue Fracture Progression through Numerical Simulations

Materials, 2023
Currently, the onset of bone damage and the interaction of cracks with the surrounding micro-architecture are still black boxes. With the motivation to address this issue, our research targets isolating lacunar morphological and densitometric effects on ...

Cyclic creep behaviour and strain classification of a bainite 2.25Cr-1Mo steel at 455oC

, 2020
Uniaxial static and cyclic creep tests are carried out on a bainite 2.25Cr-1Mo steel at 455°C. The dependence of cyclic response on varied unloading conditions is investigated, with unloading rates from 0.6 MPa/s to 39 MPa/s and the valley stress ...

Using AE based Machine Learning Approaches to Forecast Rupture during Rock Deformation Laboratory Experiments

, 2021
The ability to detect precursors of dynamic failure in brittle rocks has key implications for hazard forecasting at the field scale. In recent years, laboratory scale rock deformation experiments are providing a wealth of information on the physics of ...

Traumatic brain injury of childhood

Journal of Fatima Jinnah Medical University, 2021
It is a common observation, and very unfortunate one, that only the driver wears or “bears” helmets on motorbikes. None of the other passengers, especially children, are supposed to be protected against head injury.

Material Influence on Crenellation Effectiveness in Damage Tolerant Design

, 2017
Crenellation is a novel concept to heighten the fatigue resistance of the airframe structures without increasing weight. In this work the impact of materials on the effectiveness of crenellations was investigated. Two candidate alloys for future fuselage
