Metallic materials-Charpy notch impact test GB/T229-1994金属夏比缺口冲击试验方法
It expatiated the effects of the factors, such as sample size, temperature, humidity, notch and etc, on the result of the plastic impact strength test. 阐述了试样尺寸,温度、湿度、缺口以及缺口加工方式等因素对塑料冲击强度测试结果的影响。
How to select temperature of charpy notch impact test and up to standard about test sample of materials, welding qualifications and product of steel pressure vessels is a problem of paying close attention. 钢制压力容器的母材力学性能试件、焊接工艺评定试件和产品焊接试件的冲击试验温度和合格指标如何确定,说法不一。
Stress field analysis at notch of standard impact test sample by fem 标准冲击试样缺口应力场有限元分析
By using the thermo-simulation and Charpy-V notch impact test along with observation of the microstructures in the cleavage crack is initiated, the effect of manganese on the toughness of various zones in C-Mn multipass weld metals is investigated. 本文通过热模拟、夏氏冲击及启裂源组织观察等实验,研究了锰对C-Mn钢多层焊缝韧性影响的机理。
