2D RANDOM ORIENTED FIBER MODEL CREATION DEVICE, 2D RANDOM ORIENTED FIBER MODEL CREATION METHOD, AND 2D RANDOM ORIENTED FIBER MODEL CREATION PROGRAM

摘要

The present invention creates a 2D random oriented fiber model without increasing the number of beam elements. A 2D random oriented fiber model creation device is provided with: a random disposition quasi-isotropic fiber unit model creation unit for disposing, at random, a plurality of basic fiber models constituted of a plurality of nodes and a plurality of beam elements on a fiber area frame composed by arranging joint frames with no gap while satisfying quasi-isotropy; and a superposition unit for superposing, while maintaining a positional relationship between the respective joint frames and the nodes and beam elements within the respective joint frames, the nodes and the beam elements within the respective joint frames without being rotated, in such a manner that all remaining joint frames are overlapped with a center area frame as one of the joint frames, thereby creating a 2D random oriented fiber model area.
