Abstract Emerging memristor synapses with ion dynamics have the potential to process spatiotemporal information and can accelerate development of energy‐efficient neuromorphic computing. However, conventional ion‐migration‐type memristors suffer from low switching speed uncontrollable conductance modulation, hindering hardware implementation.

Abstract High‐detectivity and stable photodetectors (PDs) have been intensively concerned in the field of wireless optical communication, among which perovskite material has become a prospective candidate owing to its outstanding photoelectric properties. However, defects mismatched energy levels can significantly reduce detectivity stability PDs. Herein, CsPbBr 2 I quantum dots (CQDs) with surface modulation via potassium trifluoroacetate (KTFA) are utilized deserve high‐detectivity The for...
Bolted joints are commonly used for assembling carbon fiber/resin composite structures. Since drilling may generate defects at hole edges which affect mechanical properties, it is of great engineering significance to develop proper repair methods restore the properties defective parts. However, there few studies on edge and their methods. Therefore, a novelty short fiber filling method was proposed holes in this study. The intact, repaired countersunk were compared investigated. Experimental...
Predicting elastic properties of braided composites is useful in aerospace structures. In order to predict the precisely, fiber undulation and pores matrix must be considered during calculation process. For matrix, they are as inclusions a kind isotropic material. Based on inclusion theory, Mori-Tanaka method used Young's modulus pore matrix. Stiffness averaging gives estimated value parallel loading direction which contains undulation. Finally, effective representative volume element (RVE)...

Abstract In this paper, a three‐dimensional finite element (FE) model based on an anisotropic elastoplastic damage is established to simulate the impact dent of composite laminates subjected low velocity (LVI) by implementing user‐defined subroutine VUMAT in Abaqus/Explicit. To validate FE model, numerical results are compared with experimental data terms depth, contact force‐time response, and projected delamination shape. The simulation shows that considering tension‐compression asymmetry...
