Investigating Fracture Behavior of Lattice Structures Using the XFEM and Equivalent Solid Material Model Techniques

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT This study aims to numerically investigate the mode I, II, and III fracture behaviors of additively manufactured degradable, bioplastic polylactic acid (PLA) lattice specimens. Numerical simulations were performed using the eXtended Finite Element Method (XFEM) based on the extracted PLA's mechanical and fracture material properties.

Franco‐British Bilateral Diplomacy After Brexit, 2020–2025: Mending the Ties That Bind

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract Brexit shook to its very core one of the European Union's (EU's) prominent partnerships, the Franco‐British bilateral relationship (FBBR), disrupting diplomatic routines and shattering interpersonal trust before circumstances changed and the relationship rapidly began to mend. In this article, we analyse the breakdown and restoration of Franco‐

Asymmetric Regulatory Embeddedness and Post‐Brexit Governance: Explaining Adaptive Convergence in the United Kingdom

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract Why has the United Kingdom repeatedly restored substantive compatibility with European Union (EU) regulatory norms despite formal withdrawal? This article introduces the concept of asymmetric regulatory embeddedness (ARE) to explain post‐membership governance in highly integrated sectors. ARE captures the structural condition in which a former

Construction Method and Process Optimization of Prestress Reverse Tensioning for Large-Span Bidirectional Suspension Steel Roof Structures

open access: yesAdvances in Civil Engineering
For medium and small-scale steel structure stadiums, in order to minimize the impact of the construction process on the structural state, a prestressing construction process tailored to medium and small stadiums is proposed, taking full advantage of the ...

Size‐, sex‐ and site‐dependent morphological variation in the stone flounder (Kareius bicoloratus) from Korean coastal waters

open access: yesJournal of Fish Biology, EarlyView.
Abstract Kareius bicoloratus is a commercially important flatfish in Korean coastal fisheries and an ecologically relevant benthic species in nearshore ecosystems. To evaluate how multiple biological and environmental factors jointly shape flatfish morphology, we analysed 81 morphometric indices and two‐dimensional geometric morphometrics (GMM) in wild

Role of the tomato MARS1/ROUGH gene encoding a LYSINE‐SPECIFIC HISTONE DEMETHYLASE 1 in adventitious root and fruit skin formation

open access: yesJournal of Integrative Plant Biology, EarlyView.
The tomato mars1/rough mutant displays enhanced root regeneration and rough fruits due to ectopic cell proliferation. The causal gene encodes a lysine‐specific histone demethylase that normally maintains gene silencing. Its loss alters histone methylation, upregulating several genes, including those B‐type cyclins involved in tissue‐specific cellular ...

The Voronoi diagram in structural optimisation [PDF]

open access: yes, 2008
In the course of the exploration of computational means in the architectural design process, in order to investigate more complex, adaptive geometries, the Voronoi diagram has recently gained some attention, as a structure that is modular but not ...
