Microstructure‐Controlled Crack Propagation and Fracture Resistance in MoSiBTiC Alloy Revealed by Multiscale Extended Finite Element Method Modeling

open access: yesAdvanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...

The inverse nodal problem for a differential operator with an eigenvalue in the boundary condition

open access: yesApplied Mathematics Letters, 2008
The paper considers the Sturm-Liouville problem given by the second-order ODE \[ y''(x)+ [\lambda^2+ \mu- q(x)]y(x)= 0,\qquad x\in (0,\pi)\tag{1} \] subject to the boundary conditions \[ y(0)= 0,\quad ay'(\pi)+\lambda y(\pi)= 0,\tag{2} \] where \(q\in L^1([0,\pi])\), \(\mu\in \mathbb{R}\), \(a\in\mathbb{R}^*\), \(\lambda\) is eigenvalue.

Inverse nodal problems for the Sturm–Liouville operator with a constant delay

open access: yesJournal of Differential Equations, 2014
The inverse nodal problem is studied for the differential equation \[ -y''(x)+q(x)y(x-a)=\lambda y(x),\; x\in(0,\pi) \] with two-point separated boundary conditions. A procedure for constructing the solution of this problem is suggested, and the stability of the solution is established.

SPECTRAL PROPERTIES AND INVERSE NODAL PROBLEMS FOR SINGULAR DIFFUSION EQUATION

open access: yesHacettepe Journal of Mathematics and Statistics
In this study, some properties for the pencils of singular Sturm-Liouville operators are investigated. Firstly, the behaviors of eigenvalues were learned, then the solutions of the inverse problem were given to determine the potential function and parameters of the boundary condition with the help of a dense set of nodal points and lastly we obtain a ...

Inverse Nodal Problem for Sturm- Liouville Boundary Value Problem

open access: yesIğdır Üniversitesi Fen Bilimleri Enstitüsü Dergisi
Inverse nodal problems has been studied for Sturm-Liouville equations with point δ coaction. First, the eigenvalues of the problem are obtained. Then, the solution of the inverse problem is given by obtaining potential function and the parameters in the boundary conditions with the help of a dense set of nodal points.
