The tool can also analyze beams that change material or shape after reaching a support to account for changes in longer beams across the airframe.
Such models are computationally expensive and therefore impractical.
On the other hand, stresses at sharp weld corners obtained from 3D coarse FE meshes are inaccurate and cannot be used directly for fatigue life estimations.
A new integration rule has been proposed for theintegration of stress distributions through cracked concretesections or cracked and crushed concrete sections.
This thesis, by Nanette South Clark, was presented to the Department of Civil Engineering at Idaho State University in December 2005.
