Research Abstract |
A parameter U*, which is independent of stress and strain, has been introduced by the authors for expressing load transfer and load paths in a given structure. The conventional U* cannot be calculated for a point under distributed displacement. To overcome this difficulty, a new parameter U** was developed. A mathematical formulation with complementary energy and stiffness matrices was demonstrated, which can be used for efficient computation of U**. The parameter U** was used for expressing load transfer in the case of a passenger car body under the condition of the bending vibration.
