| Abstract: |
| Based on analytic structural mechanics,the interface of the two nearest sub-structures extends to a region with a certain width,named inter-belt,where the inter-belt theory and the corresponding algorithm under the framework of symplectic system can analyze the nonlocal characteristic of structures.The inter-belt theory is firstly applied in the analysis of discrete system and achieves succeed,which demonstrates the veracity and feasibility of the theory.The discrete system partitions sub-structures by inter-belt width (the region of influence),hence the minimum step-size of section integral is restricted; however the integral operation of continuous system needs arbitrary step-size.By presenting the step-increase algorithm,the inter-belt theory can deal with the integral problem of continuous system with arbitrary step-size.Numerical examples are carried out to demonstrate the validity of the theory and algorithm developed.As a basic research work,the present study illustrates well the potential of the inter-belt theory and is valuable for the further research in analytic dynamics. |
