Stresses at sharp corners rise towards infinity as the mesh size is reduced. However the forces have to balance in a Finite Element model regardless of the mesh size used. In these studies SCL (Stress Classification Line) results are compared a different mesh sizes .
Error plots show how well the complexity of a mesh matches the complexity of the model. Once a match is made the reported error is low.
This report examines the accuracy of stress results near an area of discontinuity as the mesh is refined.
How do ASME permissible fatigue curves compare to actual fatigue life results? Can they be used to predict the expected life of equipment?
Finite Element Analysis (FEA) can usually be used to support pressure equipment design submissions where the configuration is not covered by the available rules in the ASME code. Requirements vary by province.
Two common areas of high error in a FEA report are under bolt heads and at surface to surface contacts. This article explains in more depth why this happens.
Design and analysis of flanges in SolidWorks simulation often requires the use of a half bolt connector.
This solar reflector uses a vacuum to pull the front and back surfaces together to focus the reflective surface. The deflected surface shape can be calculated using FEA, but the correct shape can only be computed with large deflection theory.
Use of 2nd order integration elements is more than a requirement, it also produces the best results.
Reaction forces are the resulting loads seen at the restraints of a model being analyzed. They can be used to ensure an analysis is restrained from rigid body motion, and is static or in balance.
