Novelly-designed thin-wall TRC shells are tested simulating service loads. The study tracks the main damage modes (cracking/interfacial delamination) using the Acoustic emission (AE) wave parameter trends and based on it, a novel multi-sensing and multi-input (experiments/simulations) methodology is built. It is shown that stronger shell curvature influences the stress field and the damage mode towards shear, something monitored by early AE even before visible cracks occur, while boundary conditions and the textiles volume content also have an effect on the TRC shell damage progress. The AE inspection efficacy is critically assessed considering the detrimental wave attenuation effect.

设计新颖的薄壁 TRC 外壳经过模拟服务载荷的测试。该研究使用声发射 (AE) 波参数趋势跟踪主要损伤模式（开裂/界面分层），并在此基础上构建了一种新型的多传感和多输入（实验/模拟）方法。结果表明，更强的壳曲率会影响应力场和剪切损伤模式，早期 AE 甚至在可见裂纹出现之前就监测到了这一点，而边界条件和纺织品体积含量也对 TRC 壳损伤进程有影响。考虑到有害的波衰减效应，对 AE 检查效率进行了严格评估。
