A New Approach for Numerical Fatigue Life Prediction of Parts or Systems with Seam Welds 2003-01-2772
Recently, LMS has developed a new approach for fatigue life prediction of seam welds, which automatically combines quite accurate solid element based techniques with fast shell element-based structural analysis. Pre-modeled welded joint details are delivered in a user-extensible library, which is combined with regular shell element meshes as used in the transportation industries. Detection of the seam welds in the structure is mostly automatic.
This new approach is implemented in LMS Virtual.Lab, the integrated environment for functional performance engineering.
