Growth and Deformation Simulation of Aluminum Bronze Grains Produced by Electron Beam Additive Manufacturing

open access: yesMetals, 2022
When working out 3D building-up modes, it is necessary to predict the material properties of the resulting products. For this purpose, the crystallography of aluminum bronze grains after electron beam melting has been studied by EBSD analysis methods. To

Couplings between a collection of BF models and a set of three-form gauge fields

open access: yes, 2007
Consistent interactions that can be added to a free, Abelian gauge theory comprising a collection of BF models and a set of three-form gauge fields are constructed from the deformation of the solution to the master equation based on specific ...

T-duality and $\alpha'$-corrections [PDF]

open access: yes, 2015
We construct an $O(d,d)$ invariant universal formulation of the first-order $\alpha'$-corrections of the string effective actions involving the dilaton, metric and two-form fields.

Hydrofoil optimization of underwater glider using Free-Form Deformation and surrogate-based optimization

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2018
Hydrofoil is the direct component to generate thrust for underwater glider. It is significant to improve propulsion efficiency of hydrofoil. This study optimizes the shape of a hydrofoil using Free-Form Deformation (FFD) parametric approach and Surrogate-

R-Symmetries and Curvature Constraints in A-Twisted Heterotic Landau–Ginzburg Models

open access: yesParticles, 2023
In this paper, we discuss various aspects of a class of A-twisted heterotic Landau–Ginzburg models on a Kähler variety X. We provide a classification of the R-symmetries in these models which allow the A-twist to be implemented, focusing on the case in ...

On the generalized Freedman-Townsend model

open access: yes, 2007
Consistent interactions that can be added to a free, Abelian gauge theory comprising a finite collection of BF models and a finite set of two-form gauge fields (with the Lagrangian action written in first-order form as a sum of Abelian Freedman-Townsend ...

A new sinusoidal shear deformation theory for bending, buckling, and vibration of functionally graded plates [PDF]

open access: yes, 2012
A new sinusoidal shear deformation theory is developed for bending, buckling, and vibration of functionally graded plates. The theory accounts for sinusoidal distribution of transverse shear stress, and satisfies the free transverse shear stress ...
