Geometric Optimization and Mechanical Performance Enhancement of Auxetic Structures for High‐Impact Applications Through Fused Deposition Modeling

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the mechanical performance of three auxetic structures, identifying a re‐entrant‐star hybrid as the most effective for impact absorption. Finite element simulations and experiments demonstrate significant gains in energy absorption and flexural strength after geometric optimization. This study investigates the mechanical performance

ONE DIMENSIONAL COMBUSTION FREE BOUNDARY PROBLEM [PDF]

open access: yesGlasgow Mathematical Journal, 2004
Summary: A free boundary problem for a parabolic system arising from the mathematical theory of combustion is considered in the one-dimensional case. The existence and uniqueness of the classical solution local in time is obtained by the use of a fixed point theorem.

Two-phase problems with distributed sources: regularity of the free boundary [PDF]

open access: yes, 2012
We investigate the regularity of the free boundary for a general class of two-phase free boundary problems with non-zero right hand side. We prove that Lipschitz or flat free boundaries are $C^{1,\gamma}$.

Enabling Digital Continuity in Virtual Manufacturing for Eco‐Efficiency Assessment of Lightweight Structures by Means of a Domain‐Specific Structural Mechanics Language: Requirements, Idea and Proof of Concept

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents a solver‐agnostic domain‐specific language (DSL) for computational structural mechanics that strengthens interoperability in virtual product development. Using a hierarchical data model, the DSL enables seamless exchange between diverse simulation tools and numerical methods.

Mathematical modelling of filtration processes in drainage systems using conformal mapping

open access: yesJournal of Water and Land Development, 2018
The situation when groundwater considerably rises above the “normal” level, water intake, lowering of groundwater levels and other relevant practical tasks require the drainage facilities.

A parabolic free boundary problem with Bernoulli type condition on the free boundary [PDF]

open access: yes, 2006
Consider the parabolic free boundary problem $$ \Delta u - \partial_t u = 0 \textrm{in} \{u>0\}, |\nabla u|=1 \textrm{on} \partial\{u>0\} . $$ For a realistic class of solutions, containing for example {\em all} limits of the singular perturbation ...
