Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Considerations on double porosity structure for micropolar bodies
AIP Advances, 2015 In this study we want to extend the results of B. Straughan, which quite recently addressed the issue of double porosity structure for classical elastic bodies. In this case, the double porosity structure of the body is not influenced by the displacement

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy
Advanced Engineering Materials, EarlyView.This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Effects of pressure and fluid properties on P-wave velocity and attenuation of tight sandstones
Frontiers in Earth Science, 2023 Tight reservoirs are distributed in several basins in China, with great exploration prospects and high production potential. These reservoirs have low porosity and permeability and a significant spatial heterogeneity, and this complexity requires new ...

Multimodal Data‐Driven Microstructure Characterization
Advanced Engineering Materials, EarlyView.A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Slow P-Wave Attenuation Yielding From Berea Sandstone With Double Porosity
GeofluidsDouble porosity model differentiates fluid pressure between contact of grains (COG) and the main pore space. This study is motivated by determining phase velocity (Vps) and the quality factor (Qps) of slow P-wave for double porosity rock.
