Welded structure

In this example we consider a sub-model of a welded structure.


The sub-model is cut from a larger model subjected to 5 load components, predominantly in-phase with one exception.


The example can be used to test the hotspot extrapolation routines implemented in Fatlab, as shown below. Here, the user picks out a number of nodes and Fatlab extrapolates the stresses along the path defined by these nodes. Both IIW exptrolation (0.4t + 1.0t) and DNV extrapolation (0.5t + 1.5t) along with several others are supported.


Different SN curves can be selected for the different hotspots for comparison or sensitivity study. The results include damageutilization and dominating load component (DLC).
