The Structural Refinement of Commercial‐Purity Copper Processed by Equal Channel Angular Pressing with Low Strain Amplitude

open access: yesAdvanced Engineering Materials, EarlyView.
Equal channel angular pressing of commercial pure copper under low strain amplitude (≈0.48) induces concurrent continuous and localized discontinuous dynamic recrystallization, forming a duplex structure influenced by strain heterogeneity and recovery. Moderate hardening after 4–12 passes results from progressive high‐angle grain boundary formation via

Machine Learning‐Based Design of 3D‐Printable Microneedles for Enhanced Tissue Anchoring with Reduced Tissue Damage

open access: yesAdvanced Engineering Materials, EarlyView.
A machine learning‐driven framework is introduced to optimize 3D‐printable microneedles for enhanced tissue anchoring and reduced insertion damage. The optimized design achieves a 6.0‐fold improvement in pull‐out‐to‐penetration energy ratio over conventional shapes.

Thickness variation parameter in a thin rotating disc by finite deformation [PDF]

open access: yesFME Transactions, 2013
Seth’s transition theory is applied to the problems of thickness variation parameter in a thin rotating disc by finite deformation. Neither the yield criterion nor the associated flow rule is assumed here.

Multi-block technique applied to Navier-Stokes equations in two dimensions

open access: yesSemina: Ciências Exatas e Tecnológicas, 2018
In this work, numerical solutions of the two-dimensional Navier-Stokes and Euler equations using explicit MacCormack method on multi-block structured mesh are presented for steady state and unsteady state compressible fluid flows.

Nonlinear Hodge maps

open access: yes, 2000
We consider maps between Riemannian manifolds in which the map is a stationary point of the nonlinear Hodge energy. The variational equations of this functional form a quasilinear, nondiagonal, nonuniformly elliptic system which models certain kinds of ...

Compressible magnetogasdynamic channel flow

open access: yesZeitschrift für angewandte Mathematik und Physik ZAMP, 1964
Die stationare Stromung eines kompressiblen, elektrisch leitenden Mediums in einem Kanal wird in einfachster Weise als eindimensionales Problem behandelt,wobei die elektrische Leitfahigkeit als skalare Funktion eingefuhrt ist. Felder und Querschnittsverlauf sind als nicht konstant angenommen.

Evaluation Strategies of Hil48 Yield Criterion in Application: Toward Sufficient and Necessary Conditions for Prediction of Plastic Anisotropy

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents a comprehensive analysis of the intrinsic relationships and applicability of Hill48 yield criterion. The applicability and error evaluation conditions for Hill48 are established based on specific experimental data. A parameter calibration strategy for N‐value based on error minimization is proposed, and the predictive accuracy is ...
