Climatic Response of Densitometric Properties in Semiarid Site Tree Rings

, 1986
X-ray densitometry has proven useful in dendroclimatic research on relatively fast growing, complacent trees in mesic climates. The best dendrochronological materials, however, come from semiarid-site conifers that grow very slowly, have missing rings ...

Fine-scale canopy-mediated heterogeneity shapes the agroecological potential of Mediterranean olive groves

Frontiers in Sustainable Food Systems
Mediterranean agroecosystems are increasingly exposed to climate change, with warming and hydro-climatic extremes threatening soil fertility, water regulation and ecosystem resilience.

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

Advanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Additive Manufacturing of Continuous Fibre Reinforced Composites: Process, Characterisation, Modelling, and Sustainability

Advanced Engineering Materials, EarlyView.
Additive manufacturing provides precise control over the placement of continuous fibres within polymer matrices, enabling customised mechanical performance in composite components. This article explores processing strategies, mechanical testing, and modelling approaches for additive manufactured continuous fibre‐reinforced composites.

Density of the Commensurability Groups of Uniform Tree Lattices

Journal of Algebra, 1994
Let \(G\) be a group and \(\Gamma_ 0\), \(\Gamma_ 1\) subgroups of \(G\). The groups \(\Gamma_ 0\) and \(\Gamma_ 1\) are called commensurable if the intersection \(\Gamma_ 0 \cap \Gamma_ 1\) has finite index in both. The commensurator \(C_ G(\Gamma)\) of a subgroup \(\Gamma\) is the group of all \(g \in G\) such that \(\Gamma\) and \(g\Gamma g^{-1 ...

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.
