Product Overview ANSYS? nCode DesignLife? Integrated within ANSYS Workbench 11.0 SP1 environment to provide a leading solution for advanced fatigue analysis. ANSYS nCode DesignLifeTM Streamlining the Virtual Engineering Process Powerful Fatigue Analysis Technology Integrated Reporting and Process Encapsulation Fast, Expandable, and Scalable What is fatigue? Catastrophic failure of pressurized fuselage causes total structural collapse de Havilland Comet In short, fatigue is failure due to crack growth caused by repeated cycles of loading. Weakness in metals etc. from variations in stress. The New Little Oxford Dictionary Failure under a repeated or otherwise varying load which never reaches a level sufficient to cause failure in a single application. The initiation and growth of a crack, or growth from a pre-existing defect, until it reaches a critical size. Can durability be assessed from only a stress analysis? Why perform fatigue analysis? Sometimes it can. Some designs are driven by factors other than fatigue. When that is the case, a satisfactory fatigue life may be proven using a simple stress limit. Some parts only experience very simple loading conditions. Here again, a simple fatigue calculation may be satisfactory. However, when a structural component has multiple loads that vary with time, a simple stress limit can lead to incorrect critical locations and/or an overdesigned part. ANSYS? nCode DesignLife?
