Fixed point theorems for F-expanding mappings

Fixed Point Theory and Applications, 2017
Recently, Wardowski (Fixed Point Theory Appl. 2012:94, 2012) introduced a new concept of F-contraction and proved a fixed point theorem which generalizes the Banach contraction principle.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

Advanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Extended unified interpolative and hybrid ( α , β , F ) $(\alpha ,\beta ,F)$ contractions in metric spaces and applications to integral equations

Fixed Point Theory and Algorithms for Sciences and Engineering
This paper develops a unified and extended framework for contraction-type mappings in metric spaces by introducing extended unified interpolative Ćirić–Reich–Rus type ( α , β , F ) $(\alpha ,\beta ,F)$ -contractions together with their r-order ...

The influence of contraction duration in muscle energy technique applied to the atlanto-axial joint [PDF]

, 2004
Background: Muscle Energy Technique (MET) has been advocated for the treatment of restricted range of motion in the upper neck. There is little evidence, however, to support the effectiveness of MET to increase motion in the cervical spine, or determine ...

Air‐Pressure–Actuated Vibroacoustic Metamaterial With Tunable Bandgap: Design, Modeling, and Characterization

Advanced Engineering Materials, EarlyView.
This article presents the design, modeling, and characterization of air‐pressure–actuated programmable vibroacoustic metamaterials (PVAMM). The study focuses on leveraging air pressure to dynamically tune resonance frequencies for effective noise attenuation.

SOME NEW OBSERVATIONS ON $w$-DISTANCE AND $F$-CONTRACTIONS

Matematički Vesnik
Summary: The aim of this paper is to present some new observations about \(w\)-distance (in the sense of \textit{O. Kada} et al. [Math. Japon. 44, No. 2, 381--391 (1996; Zbl 0897.54029)]) and \(F\)-contractions (in the sense of \textit{D. Wardowski} [Fixed Point Theory Appl. 2012, Paper No. 94, 6 p. (2012; Zbl 1310.54074)]).

Some Common Fixed Point Theorems for Generalized F-Contraction Involving w-Distance with Some Applications to Differential Equations

Mathematics, 2018
In this paper, we introduce the Ćirić type generalized F-contraction and establish certain common fixed point results for such F-contraction in metric spaces with the w-distances. In addition, we give some examples to support our results.
