Deforming Locally Convex Curves into Curves of Constant $k$-order Width [PDF]

arXiv
A nonlocal curvature flow is introduced to evolve locally convex curves in the plane. It is proved that this flow with any initial locally convex curve has a global solution, keeping the local convexity and the elastic energy of the evolving curve, and that, as the time goes to infinity, the curve converges to a smooth, locally convex curve of constant

Process Parameter and Dimension‐Dependent Mn Vaporization During Laser Powder Bed Fusion of an Fe–Mi–Si–Cr‐Based Shape Memory Alloy

Advanced Engineering Materials, EarlyView.
The functional properties of Fe–Mn–Si–Cr‐based shape memory alloys are influenced, among other things, by their chemical composition. Here, the vaporization of Mn, the most volatile element of the alloy, is investigated. It is shown that the process parameters make noninterchangeable contributions to the vaporization and that vaporization differences ...

Damage State of Non-Engineered Residential Buildings Owing to Earthquakes: A Case Study in Pacitan Regency, Indonesia

Civil and Environmental Engineering
The Pacitan Regency of Indonesia is located in an area of high seismic activities. Regrettably, field surveys held in Pacitan Regency, Indonesia have revealed the prevalence of low-income housing structures that do not meet the engineering standards and ...

Residual Stress States in Microstructurally Graded PBF–LB/M Austenitic Steel Components

Advanced Engineering Materials, EarlyView.
This study examines microstructurally graded 316L rectangular tube profiles fabricated via PBF–LB/M using a dual‐laser system. A 1 kW top‐hat and a 400 W Gaussian laser create distinct grain sizes and crystallographic texture. Mechanical properties are linked to microstructural evolution driven by processing conditions.

Toughness of Confined Auxetic Foams

Advanced Engineering Materials, EarlyView.
Auxetic (negative Poisson's ratio) materials offer benefits such as impact mitigation, thermal insulation, vibration damping, and reduced shear strain, although their fracture mechanics are largely unexplored. This study investigates damage initiation and propagation in confined re‐entrant auxetic foams from polyurethane via experimental ...

Discontinuous depinning/yielding transition of elastic manifolds with tailored internal elasticity [PDF]

arXiv
We consider elastic manifolds evolving on disordered energy potentials under the action of an external uniform driving. This scenario includes the cases of {\em depinning} and {\em yielding}, which provide paradigmatic examples of out of equilibrium phase transitions.
