Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

open access: yesAdvanced 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.

Elimination of Implant-Induced Distortions in Computed Tomography Images

open access: yes, 2012
Hip implants, pacemakers, and other metal implants can cause considerable distortions in computerized axial tomography computed tomography (CT) or computerized axial tomography scans.

Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Do tax distortions lead to more indeterminacy? A New Keynesian perspective [PDF]

open access: yes
Following the recent developments of the literature on stabilization policies, this paper investigates the effect of tax distortions on equilibrium determinacy in a New Keynesian economy with rule-of-thumb consumers and capital accumulation.

REPRESENTAÇÃO E DISTORÇÕES CONCEITUAIS DO CONTEÚDO "FILOGENIA" EM LIVROS DIDÁTICOS DE BIOLOGIA DO ENSINO MÉDIO

open access: yesEnsaio Pesquisa em Educação em Ciências, 2012
Biology textbooks have been frequently used as the only content resource, characterized by a fragmentary organization. This research aimed to analyze the insertion of the topic "Phylogeny" in textbooks, searching for conceptual distortions and approaches

Multimodal Data‐Driven Microstructure Characterization

open access: yesAdvanced 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.
