Prediction of Cure‐Induced Wrinkles Aimed at the Manufacturing of Large Wind Turbine Blades

Polymer Composites, EarlyView.
The step‐wise progression of the development of cure‐induced wrinkles. Before curing, at room temperature the laminate is resting at the mould face. In the next step, the wrinkle is developing due to thermal gradients. At the end of curing, the composite has cooled down and the undulation is left in, byt the increase in resin stiffness across the ...

Kinship through code, personhood as node: AI afterlives and new technologies of the self Parenté par le code, personne nodale : vie posthume dans l'IA et nouvelles technologies du moi

Journal of the Royal Anthropological Institute, EarlyView.
This article examines how emerging generative AI technologies in Europe and North America are being used to reanimate the dead, prompting users to define the ‘edges’ of self and personhood through coding practices. These technologies invite new engagements with fundamental questions of relatedness and the construction of the self, challenging and ...

Computational Investigation on the Combined Effect of Applied Strain and Pore Configuration on Strain Concentrators in Additively Manufactured Metals

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Metal additive manufacturing (AM) provides a pathway for creating highly optimized components that would be difficult to produce using traditional manufacturing methods. However, regardless of printing parameters or postprocessing, porosity remains a prevalent challenge in AM components because strain concentrates in the vicinity of the pore ...

Analysis of the vibration of pipes conveying fluid [PDF]

, 1999
The dynamic equilibrium matrix equation for a discretized pipe element containing flowing fluid is derived from the Lagrange principle, the Ritz method and consideration of the coupling between the pipe and fluid. The Eulerian approach and the concept of

Timelike self-similar spherically symmetric perfect-fluid models [PDF]

, 1998
Einstein's field equations for timelike self-similar spherically symmetric perfect-fluid models are investigated. The field equations are rewritten as a first-order system of autonomous differential equations. Dimensionless variables are chosen in such a
