利用爆炸加载数字激光动态焦散线试验系统,进行双孔爆破爆炸应力波作用下缺陷介质裂纹扩展试验。研究了含水平预制裂纹和竖直预制裂纹的介质裂纹扩展路径、速度、加速度和裂尖动态应力强度因子变化规律。试验结果表明:在爆炸应力波作用下,预制裂纹尖端起裂,并扩展。炸药爆炸后,主裂纹的扩展速度迅速达到峰值,之后开始振荡减小,其加速度呈现波浪起伏式的振荡变化。次裂纹起裂后速度增大至峰值,然后开始减小。主裂纹尖端的动态应力强度因子K_Ⅰ从峰值振荡减小,又振荡增加至第二个峰值,之后振荡减小。次裂纹尖端的动态应力强度因子K_Ⅰ达到最大时,次裂纹起裂,之后K_Ⅰ振荡减小。裂纹扩展的过程中K_Ⅱ基本都小于K_Ⅰ。

由于地下介质对地震波能量有强烈的吸收作用,降低了地震资料的分辨率以及地震资料处理、解释的精度,因此选择合适的参数对地层吸收衰减情况进行有效描述是对地下构造进行高分辨率、高精度处理及解释的有效途径。目前品质因子Q是对岩石弹性参数进行有效描述的重要参数之一。用品质因子Q来衡量地震波能量在介质中传播的吸收衰减情况,是目前提高地震资料分辨率的有效方法,同时也是提高含油气地层解释精度的有效途径。近些年,许多学者提出了多种计算Q值的方法,其中谱比法是在实际中应用最为广泛的Q值估计方法。本文在前人方法的基础上,对谱比法进行了改进,并结合走时层析方法反演Q值,充分利用谱比法在精度、稳定性等方面的优势以及走时层析方法计算效率高的优点,不仅可以提高反演的精度而且能够保证反演的稳定性,提高计算效率。通过模型试算证明谱比法衰减层析方法能有效估计Q值变化情况,具有较好的发展前景。

Polymeric microwave actuators combining tissue-like softness with programmablemicrowave-responsive deformation hold great promise for mobile intelligentdevices and bionic soft robots. However, their application is challenged by restricted electromagneticsensitivity and intricate sensing coupling. In this study, a sensitized polymericmicrowave actuator is fabricated by hybridizing a liquid crystal polymer with Ti3C2Tx(MXene). Compared to the initial counterpart, the hybrid polymer exhibits unique spacechargepolarization and interfacial polarization, resulting in significant improvements of230% in the dielectric loss factor and 830% in the apparent efficiency of electromagneticenergy harvest. The sensitized microwave actuation demonstrates as the shortenedresponse time of nearly 10 s, which is merely 13% of that for the initial shape memory polymer. Moreover, the ultra-low content of MXene (upto 0.15 wt%) benefits for maintaining the actuation potential of the hybrid polymer. An innovative self-powered sensing prototype that combinesdriving and piezoelectric polymers is developed, which generates real-time electric potential feedback (open-circuit potential of ~ 3 mV) duringactuation. The polarization-dominant energy conversion mechanism observed in the MXene-polymer hybrid structure furnishes a new approachfor developing efficient electromagnetic dissipative structures and shows potential for advancing polymeric electromagnetic intelligent devices.
