Fatigue crack propagation in turbine disks of EI698 superalloy

Fracture and Structural Integrity, 2013
In-service fatigue cracking of turbine disks of EI698 superalloy is discussed based on crack growth analyses. In the bolt joint for disks to shaft connecting there is high level of stress-state, which directed to earlier in-disks fatigue crack ...

Structural performance of steel-concrete sandwich beams with carbon nanofiber reinforcement [PDF]

, 2019
Cementitious materials such as concrete are typically characterised as quasi-brittle with low tensile strength and low strain capacity, which hence affect the long-term durability of the structure.

Reinforcement Strains in Reinforced Concrete Tensile Members Recorded by Strain Gauges and FBG Sensors: Experimental and Numerical Analysis

Sensors, 2019
Experimental and numerical studies have been carried out on reinforced concrete (RC) short tensile specimens. Double pull-out tests employed rectangular RC elements of a length determined not to yield any additional primary cracks. Tests were carried out

Avoidance of stress corrosion susceptibility in high strength aluminum alloys by control of grain boundary and matrix microstructure [PDF]

The relation of microstructure to the mechanical strength and stress corrosion resistance of highest strength and overaged tempers of BAR and 7050 aluminum alloys was investigated. Comparison is made with previously studied 7075 aluminum alloy.

Study on Chloride Ion Diffusion Model in Crack Zones of Saturated Concrete Structure

Zhongwai Gonglu
In order to accurately characterize the behavior of cracks in accelerating chloride ion transport on both sides of the concrete, the concept of effective influence distance of cracks was proposed, and the crack pores were non-uniformly distributed ...

Effects of bedding characteristics on crack propagation of coal under mode II loading: Laboratory experiment and numerical simulation

Journal of Rock Mechanics and Geotechnical Engineering
The fracture network of hydraulic crack is significantly influenced by the bedding plane in coalbed methane extraction. Under mode II loading, crack deflection holds a key position in hydraulic cracking, especially in hydraulic shearing. This study first

Micromechanical model of crack growth in fiber reinforced ceramics [PDF]

A model based on the micromechanical mechanism of crack growth resistance in fiber reinforced ceramics is presented. The formulation of the model is based on a small scale geometry of a macrocrack with a bridging zone, the process zone, which governs the
