Introduction of New Concept U*sum for Evaluation of Weight-Efficient Structure 2011-01-0061
A new index U*
for evaluating load path dispersion is proposed, using a structural load path analysis method based on the concept of U*, which expresses the connection strength between a load point and an arbitrary point within the structure. U*
enables the evaluation of the load path dispersion within the structure by statistical means such as histograms and standard deviations. Different loading conditions are applied to a body structure, and the similarity of the U*
distributions is evaluated using the direction cosine and U*
2-dimensional correlation diagrams. It is shown as a result that body structures can be macroscopically grasped by using the U*
distribution rather than using the stress distribution. In addition, as an example, the U*
distribution of torsion loading condition is shown to comprehensively include characteristics of the U*
