Welding is a commonly used and effective method for making structural joints between metal parts in the heavy industry. However, the nature of the welding process means that these weldments generally have a fatigue strength that is inferior to that of the parts being joined together. The result is that, even in a well-designed structure, the welded joints are likely to fatigue. Any evaluation of the durability of a welded structure must therefore place a high priority on a fatigue assessment of the welded joints.
This webinar will review underlying methodology and approaches in DesignLife for predicting the fatigue life of welds using finite element models consisting of either shell or solid elements. A demonstration will review how DesignLife can be used for predicting fatigue life using a weld definition created by HyperMesh and stress results from OptiStruct.Webinar outline:
Who should attend?
This webinar is aimed at engineers who are concerned with the structural integrity of welded structures, and who would like to understand how fatigue calculations can be performed appropriate to their structure and weld type.
HBM nCode's DesignLife is an up-front design tool that identifies critical locations and calculates realistic fatigue lives from leading finite element (FE) results for both metals and composites. Users can go beyond performing simplified stress analysis and avoid under- or over-designing products by simulating actual loading conditions to avoid costly design changes.
nCode DesignLife features advanced capabilities to rapidly deliver accurate fatigue life predictions. Major OEMs and their suppliers use DesignLife worldwide to answer questions like “how long will it last?” or “will it pass the test?” before a prototype is even made.
How is DesignLife useful to APA users?
nCode DesignLife is a complete fatigue solution for identifying critical locations and calculating fatigue lives in the time and frequency domains - from high to low cycle, uniaxial to multiaxial, crack initiation to crack growth - by using results from all leading FE codes. This provides unparalleled combination of ease-of-use and powerful fatigue analysis without additional investment for APA users.
