COMPUTER SIMULATION OF ELASTIC PROPERTIES ON ANY STRUCTURE 3-D WOVEN COMPOSITE

This paper presents the concept of yarn state, solving the descriptive problem of preform structure of any 3 D woven composite. A cross equivalent curve board model is expounded, and with the help of cubic polynomial interpolation theory, the computer simulation model is developed which reflects the constitutive relation of 3 D woven composite. In addition, contrast tests are conducted to verify the model.
