The Worksheet tab includes theoretical graphic information that reflects settings in the Details View.
Fatigue Strength Factor (Kf )
This is the fatigue strength reduction factor.The stress-life or strain-life curve(s) are adjusted by this factor when the fatigue analysis is run.This setting is used to account for a "real world" environment that may be harsher than a rigidly-controlled laboratory environment in which the data was collected.Common fatigue strength reduction factors to account for such things as surface finish can be found in design handbooks.
Non-proportional Loading (available only for stress-life applications)
The first three are all constant amplitude,proportional loading types and are illustrated with a graph in the Geometry window.
The fourth type,history data,allows you to navigate to a file containing the data points.This option is a non-constant amplitude proportional loading type.This data is depicted in a graph on the Worksheet tab.You can specify the number of data points this graph will display in the Maximum Data Points To Plot field located in the Details View of the Fatigue Tool.
The fifth option is a non-proportional constant amplitude loading type for models that alternate between two completely different stress states (for example,between bending and torsional loading).Problems such as an alternating stress imposed on a static stress can be modeled with this feature.Non-proportional loading is applicable on fatigue tools under Solution Combination where exactly two environments are selected.
Scale Factor
This setting scales the load magnitude.For example,if you set this to 3,the maximum amplitude of a zero-based curve will be 1.5 times the stress in the body.The graph in the Geometry window will update to reflect this setting.This option is useful to see the effects of different finite element loading magnitudes without having to run the complete structural analysis repeatedly.
Analysis Type
Choose either Stress Life or Strain Life.
Mean Stress Theory
This setting specifies how the mean stress effects should be handled.
If Analysis Type is set to Stress Life,choose from None,Goodman,Soderberg,Gerber,and Mean Stress Curves.The Goodman,Soderberg,and Gerber options use static material properties along with S-N data to account for any mean stress while Mean Stress Curves use experimental fatigue data to account for mean stress.The default mean stress theory can be defined through the Simulation Fatigue settings in the Options dialog box.
If Analysis Type is set to Strain Life,choose from None,Morrow,and SWT (Smith-Watson-Topper).
Note
A sample plot of each of these theories is shown at the bottom of the Worksheet view.This plot does not use live data,but is rather a generic representation of each theory.For more information on these theories,see "Metal Fatigue In Engineering" by Ralph I.Stephens,et.al.

工作表标签,包括理论的图形信息,反映了在详细查看设置.
疲劳强度因子(KF法)
这是疲劳强度折减系数.的应力应变的生命或生活的曲线(S)是由这个因素调整后的疲劳分析时运行.此设置用于一个“现实世界的帐户”的环境可能比严厉严格控制的实验室环境中数据收集.共同的疲劳强度降低因素占到表面完成这些事可以在设计手册中.
非比例加载(仅适用于应力性应用软件)
前三个都是恒幅,比例加载类型,并与在几何图所示的窗口.
第四类,历史数据,可在浏览到一个文件中包含的数据点.这个选项是一个非恒幅比例加载类型.这个数据是描述了一个工作表选项卡图.您可以指定多个数据点,该图将在最大数据点显示要绘制领域的疲劳工具的详细信息视图位置.
第五个选项是一个非恒幅比例加载类型的模型两名候补之间的完全不同(例如,在弯曲和扭转负荷)应力状态.如在一个静态应力施加的交变应力问题可以建立使用此功能.非比例加载下适用解决方案相结合何处两个环境被选中的疲劳工具.
比例因子
此设置尺度的负载大小.例如,如果您设置为3,最大振幅零的曲线将1.5倍,在体内的压力.在窗口的几何图将更新以反映此设置.这个选项是有益的,而不必运行完整的结构分析多次不同程度的有限元负载的影响.
分析类型
可选择应力应变生活或生命.
平均应力理论
此设置指定如何平均应力的影响应该予以处理.
如果分析类型设置为生活压力,选择无,古德曼,索德伯格,格柏,和平均应力曲线.古德曼,索德伯格和Gerber选项一起使用锡材料特性的静态数据交代任何压力,同时意味着平均应力疲劳试验曲线的使用数据,以平均应力.默认的平均应力理论,可以通过在选项模拟疲劳设置对话框中定义.
如果分析类型设置为应变生活,从没有,莫罗和SWT选择(史密斯沃森礼帽).
注意:
对其中的理论每样地显示在工作表视图底部.这情节不使用实时数据,而是一种通用理论,每个代表.欲了解更多有关这些理论信息,请参见“在工程金属疲劳”的拉尔夫一蒂芬斯,等.报.
