Abstract : the sensation of wearing pressure have assessed for knit garments having different sizes and fabrics having the different extensibility , by developing a wearing experimental procedure . at the same time , the objective clothing pressure , the fabric ' s extensibility and the garment ' s fitness have measured . regression analysis showed that the garment ' s fitnessand fabric ' s extensibility had great predictive power for the subjective pressure assessment 文摘:设计了一组服装用于穿着实验.对不同尺寸、不同弹性性能的紧身长裤进行了主观压力感评价,并测量了服装压、衣料的拉伸变形程度和服装宽裕率.通过分析,选用服装宽裕率和织物的弹性模量作为指标预测服装的穿着压力感
Based on investigating a large amount of documents , the fatigue crack propagation behavior of mg alloys am50 & az91 is studied in this paper , as well as the tensile mechanical properties at elevated temperature . micro - mechanics of tensile deformation and the fcpr are also investigated by sem & tem 本文在查阅大量相关文献基础上,对az91 、 am50镁合金的疲劳裂纹扩展特性和高温拉伸力学性能进行了一定的研究。借助于扫描电镜和透射电子显微镜,分析了拉伸变形和疲劳断裂的微观机制。
Analyzing the effects towards residual stress from different rolling loadcase , the value of cold rolling residual stress caused by different compress was gotten ; analyzing parameters stretching toward different rolling loadcase board , the effect of the residual stress elimination influenced by stretching force and stretching deformation was figured out 通过分析不同轧制工况对残馀应力分布的影响,得到不同压缩量对轧制残馀应力的影响; ?对不同轧制工况后的板材进行参数拉伸,得到拉伸力大小、拉伸变形量大小对残馀应力消除效果的影响值。
