Multiscale Investigation of Microcracks and Grain Boundary Wetting in Press-Hardened Galvanized 20MnB8 Steel

Metals, 2023
Grain boundary wetting as a preliminary stage for zinc-induced grain boundary weakening and embrittlement in a Zn-coated press-hardened 20MnB8 steel was analyzed using electron backscatter diffraction, Auger electron spectroscopy, energy dispersive X-ray

Stereomicroscopic evaluation of microcrack formation in dentin by protaper next, revo s, and waveone gold file system

Contemporary Clinical Dentistry, 2021
Background: During the biomechanical preparation of the root canal by rotary file systems, stress is generated within the canal, which leads to dentinal microcrack formation. Such defects are evaluated only under the microscope.

Microcracks and Osteoclast Resorption Activity In Vitro [PDF]

Calcified Tissue International, 2011
During bone remodeling osteoclasts resorb bone, thus removing material, e.g., damaged by microcracks, which arises as a result of physiological loading and could reduce bone strength. Such a process needs targeted bone resorption exactly at damaged sites. Osteocytic signaling plays a key role in this process, but it is not excluded that osteoclasts per

Mesoscopic characterization and modeling of microcracking in cementitious materials by the extended finite element method

Theoretical and Applied Mechanics Letters, 2014
This study develops a mesoscopic framework and methodology for the modeling of microcracks in concrete. A new algorithm is first proposed for the generation of random concrete meso-structure including microcracks and then coupled with the extended finite

Influence of Anisotropy Induced by Microcracks on Effectiye Elastic Properties [PDF]

, 2005
The influence of microcracks distribution on macroscopic elastic properties of composites with a specific structure is studied. The model predicts the properties of laminates made of materials in which fracture process leads to appearance of many ...

Recent advance in structure regulation of high‐capacity Ni‐rich layered oxide cathodes

EcoMat, 2021
High‐capacity layered oxide Ni‐rich cathodes are attractive to enhance the driving‐range of electric vehicles because of its preferential costs. Nevertheless, in Ni‐rich cathodes, there are still many issues such as microcracks generation along grain ...

Analysis of two-dimensional finite solids with microcracks

, 1999
A general method is presented for solving the plane elasticity problem of finite plates with multiple microcracks. The method directly accounts for the interactions between different microcracks and the effect of outer boundary of a finite plate ...
