The mean resonance frequency of the human middle ear under air conduction (AC) excitation is known to be around 0.8-1.2 kHz. However, studies suggest that bone (BC) at a higher 1.5-2 To identify cause for this difference, middle-ear responses both AC and BC excitations were measured umbo lateral process malleus using five cadaver temporal bones. modes identified from these measurements, along with finite element analysis results, indicate presence two ossicular below 2 dominant mode first...
Foreign fibers in cotton layers have a particular impact on the quality of cotton. Traditional image processing methods are ineffective detecting foreign layers, which time-consuming and costly. In order to identify effectively, classification identification method for was proposed based NIR spectroscopy CNN-TCN. this study, near-infrared ranging from 780 nm 2360 used type fibers. Savitzky-Golay smoothing preprocess data, LightGBM-ANOVA determine optimal wavelengths. Preprocessed spectral...
Tool geometry can significantly influence hole quality during drilling of CFRP laminates, which has impact on mechanical properties. In this paper, experiments with different drill bit geometries (twist, brad and dagger drill) are carried out carbon fiber reinforced polyetheretherketone (CF/PEEK) composites. The tool temperature, thrust force, hole-making analyzed. effect machining-induced damage the tensile properties CF/PEEK composites machined investigated. strain distributions around...
In this paper, we propose a discrete perfectly matched layer (PML) for the peridynamic scalar wave-type problems in viscous media. Constructing PMLs nonlocal models is often challenging, mainly due to fact that operators are usually associated with various kernels. We first convert continua model spatial semi-discretized version by adopting quadrature-based finite difference scheme, and then derive PML equations from using analytic continuation. The harmonic exponential fundamental solutions...
ABSTRACT Thermoplastic carbon fiber reinforced polyetheretherketone (CF/PEEK) composite materials have broad application prospects in the aerospace field due to their unique recyclability and reusability. This paper proposes a novel heat treatment method aimed at enhancing tensile properties of drilled CF/PEEK laminates based on crystallinity control. The thermoplastic plays pivotal role determining its mechanical properties. nonisothermal crystallization kinetics indicate that composites...
Abstract For the first time, this paper proposes a new strategy based on crystallinity control in enhancing flexural strength of drilled carbon fiber reinforced polyetheretherketone (CF/PEEK) composite laminate. The high‐positive correlation between unique crystalline characteristic CF/PEEK and its is introduced into strategy, superposition pre‐heat treatment, intermediate‐heat post‐heat treatment carried out to increase crystallinity. optimal heat temperature 320 °C identified through situ...
Abstract This paper comprehensively investigated the effect of tool geometries on heat transfer and special crystallization characteristics in drilling carbon fiber‐reinforced polyetheretherketone (CF/PEEK) composite for first time. Three tools with different (twist, brad, dagger drill) are carried out CF/PEEK experiments, temperature, as well crystallinity surface roughness, introduced to make a comparative evaluation geometries. The results show that temperature is determined by contact...
Removable joint technology is commonly used in composite laminates for various load-bearing structures. However, existing research primarily focuses on bolted joints, there relatively limited screwed joints materials. This study investigates the influence of connected layer thickness and hole diameter tensile behavior threaded carbon fiber-reinforced polymer (CFRP) laminates. After fabricating different CFRP specimens, tests were conducted. The digital image correlation (DIC) technique...
