复合材料的比模量与比强度相对金属材料比较高，热稳定性、耐疲劳性及减震性能好，所以普遍使用在航天航空、汽车、船舶工程、休闲用品等领域。在实际应用中，为保证复合材料使用过程中的安全性能，经常需要对其进行损伤检测，例如风机叶片。但由于其尺寸大、外形复杂等特点，损伤识别过程中难免会用到复合材料动力学参数，固有频率的提取便于获得分析，所以有必要通过试验来研究复合材料固有频率疲劳衰减规律。
作者应用超声疲劳试验方法测试了FV520B-I 大尺寸试样的超高周疲劳性能。试验结果表明：试样尺寸增大时,超高周疲劳机理不会发生改变,但超高周疲劳性能下降,S-N 曲线向下偏移,相同应力水平下,疲劳寿命减小,这是由于大试样中夹杂物尺寸增加导致的。采用统计极值方法预测了试样中的最大夹杂物尺寸。通过相关模型对其疲劳强度、疲劳寿命进行了预测,相较于之前对小试样试验结果的预测,疲劳强度预测更准确,而疲劳寿
Scanning electron microscopy(SEM)is of great importance for studying microstructures of porous media.From the SEM images,the capillaries and pores can be obtained by using the image segmentation.
The Weierstrass–Mandelbrot(W-M)function is the common continuous and non-differentiable function in mathematics,which can be used to describe the fractal characters of these pores in porous fibrous me
With the rapid advance of microfluidic and nanofluidic technologies,more and more applications are being developed,ranging from biotechnologies,chemistry,materials development to environmental monitor
Large amount of heat will be generated by the densely packed power batteries when an electric vehicle operates at a high charging/discharging rate.It must be dissipated timely to ensure vehicles safet
Rapid gas-liquid reactions are important for both fundamental sciences and large-scale energy and medical applications.Currently,the lack of stable and controllable gas-liquid interface limits the mas
Synergy of spatial-periodically distributed heating and roughness of channel boundary has been reported to induce fluid drift,leading to net flow rate in a channel(Abtahi and Floryan,J.Fluid Mech.,201
In the past decade there has been a markedly increasing interest in applying acoustofluidics as a tool in MEMS and lab-on-a-chip systems.In this numerical study,surface acoustic waves(SAW)are consider
