The mechanical behavior under static and fatigue loading induced by mechanical forces is examined in this article through the utilization of a non-destructive methodology. However, it is worth noting that the dynamics of elastic waves become notably more intricate when dealing with composite materials. In order to provide a comprehensive description of the green flax/epoxy system, a crucial component of this study involves the computation of guided wave dispersion curves within the test samples. By evaluating the longitudinal and shear modulus under varying stress conditions, the propagation of high-frequency ultrasonic waves, which serves as a dynamic mechanical deformation, can be leveraged to facilitate the comparison of both mechanical and ultrasonic data. The significant changes occurring during the aging process are closely associated with variations in velocity throughout the loading period. The wavelet transformation of all acquired ultrasonic echoes yields the experimental transfer function, thereby enhancing our understanding of the subject matter.

导波监测亚麻纤维增强复合材料的行为


本文利用非破坏性方法研究了机械力引起的静态和疲劳载荷下的机械行为。然而，值得注意的是，在处理复合材料时，弹性波的动力学变得更加复杂。为了提供对绿色亚麻/环氧树脂系统的全面描述，本研究的一个关键组成部分涉及测试样品内导波色散曲线的计算。通过评估不同应力条件下的纵向和剪切模量，可以利用作为动态机械变形的高频超声波的传播来促进机械和超声数据的比较。老化过程中发生的显着变化与整个加载期间的速度变化密切相关。所有采集的超声回波的小波变换产生实验传递函数，从而增强我们对主题的理解。
