Predictive Engineering Presenting at the 2014 Femap Symposium
One of our partners, Predictive Engineering Inc., will be attending and presenting at the Femap Symposium on 16th May. If you haven’t already registered, do so now and come along to hear George Laird show how Femap is used to help predict stress and fatigue of ASME pressure vessels. George will also be covering some fatigue essentials as well.
The application of the ASME Section VIII, Division 2 pressure vessel code is becoming increasingly more popular since it facilitates the optimization of pressure vessels via detailed stress and fatigue analysis. The basis of this analysis is the creation of a high quality plate and/or solid mesh followed by accurate load application and then the extraction and classification of stresses per code. Much of this work is algebraic in nature and is well suited for automation. Through the use of Femap’s Application Programing Interface (API) and customized spreadsheets, the analysis of ASME-type pressure vessels can be accelerated from days to minutes. In many cases, once the vessel has passed its baseline load requirements, a fatigue analysis is required to address cyclic mechanical and thermal loads. Although fatigue analysis can be quite basic and almost an accounting exercise, the more stringent ASME requirements of specialized fatigue curves and stress output as stress intensity complicates the procedure. To simplify this calculation, the software program Fatigue Essentials is used and a brief example is presented on how this program automates the fatigue calculation.
The Femap Symposium is being held in Atlanta, GA at the Westin Peachtree Plaza on May 14 – 16. Register now to secure your place at this great event.
