Fatigue of Welds for Heavy Equipment
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 for HyperWorks can be used for predicting fatigue life using a weld definition created by HyperMesh and stress results from OptiStruct.
