简支梁无缺口冲击强度度 是数值大好还是数值小好 能不能举个例子 谢谢

工程塑料的冲击强度冲击试验是用来度量材料在高速冲击状态下的韧性或对断裂的抵抗能力的一种试验。测试工程塑料冲击试验的方法较多,主要有摆锤冲击试验法、落锤冲击试验法。摆锤冲击试验又分简支梁(Charpy)法和悬臂梁(Izod)法。目前国内测试工程塑料冲击强度使用较多的是简支梁法,而国外则大多使用悬臂梁法。选用冲击强度数据时,应注意所采用的试验方法。简支梁冲击试验所用的试样分为无缺口和有缺口两种。(1)无缺口试样简支梁冲击强度其冲击强度是指无缺口试样在冲击载荷作用下,破坏时所吸收的冲击能量与试样的原始横截面积之比,单位为kJ/m2。(2)缺口试样简支梁冲击强度其冲击强度是指缺口试样在冲击载荷作用下,破坏时所吸收的冲击能量与试样缺口处的原始横截面积之比,单位为kJ/m2。悬臂梁冲击试验所用的试样开有缺口,以试样破断时单位宽度所消耗的能量来衡量,单位是J/m。表1-13列出了一些工程塑料的悬臂梁缺口冲击强度。什么是工程塑胶原料?http://www.gdsulong.com/News/31.html百度搜索“就爱阅读”,专业资料,生活学习,尽在就爱阅读网92to.com,您的在线图书馆
