Journal of Traumatic Stress, Volume 33, Issue 6, Page 1060-1070, December 2020., 2020 Abstract Survivors of traumatic events commonly suffer from long‐term pain and related somatic symptomatology. To test the predominant hypothesis that survivors’ pain comprises sequela of persistent posttraumatic stress symptoms (PTSS), we assessed the sequential order of symptom development among young survivors of a terrorist attack.

Jianzhu Gangjiegou Jinzhan, 2022 针对钢桥中钢板疲劳裂纹进行了一系列疲劳裂纹修复试验研究，以确定不同修复方法下结构的疲劳性能。高弹模CFRP（碳纤维增强复合材料）修复法是通过粘贴高弹模CFRP布来增大结构刚度，以延长结构疲劳寿命，且碳纤维材料基本不会产生疲劳裂纹，具有较好的抗疲劳效果。采用数值模拟和试验研究相结合的方法，首先对修复钢板的应力分布和特点进行了详细的分析，然后通过3组对比疲劳试验，确定了不同修复方法对损伤钢板疲劳寿命的增强效果。最后利用修复试验值与各国规范规定的S-N曲线进行比较，分析已修复钢板的疲劳性能。研究结果表明 ...
