Multidimensional U*sum Correlation Diagram for Body Structure Analysis

Abstract

Evaluation of body loading paths in a body structure under several loading conditions was performed using U*sum, which enables visualization of internal load paths of body structure. In order to quantitatively grasp the load path distribution characteristics of the frame parts and panel parts under two different loading conditions, an evaluation method using 2-dimensional correlation diagrams which show the U*sum distribution under each loading conditions is proposed.
