A Novel Simulation Approach for Damage Evolution during Tailored Forming
Traditional damage models are struggling to accurately and efficiently simulate large‐scale three‐dimensional models with a great number of degrees of freedoms. A new gradient‐enhanced damage model based on the extended Hamilton principle can significantly reduce the computation time while ensuring mesh‐independence which is suitable to use in tailored

(1,2)-PDS in graphs with the small number of vertices of large degrees [PDF]
We define and study a perfect \((1,2)\)-dominating set which is a special case of a \((1,2)\)-dominating set. We discuss the existence of a perfect \((1,2)\)-dominating set in graphs with at most two vertices of maximum degree.

A novel metadata schema is introduced to address the sparsity of microstructure‐sensitive mechanical data. The design follows the material modeling workflow, as each run results in the definition of unique data objects. The schema includes categorical elements to ensure findability, accessibility, interoperability, and reusability (FAIR). This approach

STROPHOIDS, A FAMILY OF CUBIC CURVES WITH REMARKABLE PROPERTIES
Strophoids are circular cubic curves which have a node with orthogonal tangents. These rational curves are characterized by a series or properties, and they show up as locus of points at various geometric problems in the Euclidean plane: Strophoids are ...

Time discretization of the spin Calogero-Moser model and the semi-discrete matrix KP hierarchy [PDF]
We introduce the discrete time version of the spin Calogero-Moser system. The equations of motion follow from the dynamics of poles of rational solutions to the matrix KP hierarchy with discrete time. The dynamics of poles is derived using the auxiliary linear problem for the discrete flow.

This article critically reviews the recent advances in the development of nanomaterial‐based inks derived from 2D nanomaterials and how the addition of 2D nanomaterials alters the rheology of different polymers for 3D printing. The review further explores the application of 3D‐printed structures in the electronics, sensor, and energy sectors.

Degree sequence for k-arc strongly connected multiple digraphs
Let D be a digraph on { v 1 , … , v n } $\{v_{1},\ldots, v_{n}\}$ . Then the sequence { ( d + ( v 1 ) , d − ( v 1 ) ) , … , ( d + ( v n ) , d − ( v n ) ) } $\{ (d^{+}(v_{1}), d^{-}(v_{1})), \ldots, (d^{+}(v_{n}), d^{-}(v_{n}))\}$ is called the degree ...

On mathematics and discrete space
The ancient Greek philosophers – like Parmenides – reasoned that observable reality cannot exist by itself. It has to be a creation of an underlying reality. An all-inclusive existence that has a structure because observable reality shows structure at every scale size. Although observable reality is involved in a continuous transformation too.
