Feature Based Modeling of Heterogeneous Objects

Xiaojun Wu, Weijun Liu, Michael Yu Wang

The representation of Heterogeneous Object (HO) is divided into two categories: Data model (DM) and material evaluation paradigm (MEP). A hybrid methodology with geometry model…

Interval Factor Method for Interval Finite Element Analysis of Truss Structures

Ma Juan, Chen Jian‐jun, Zhang Jian‐guo, Jiang Tao

The uncertainty of the interval variable is represented by interval factor, and the interval variable is described as its mean value multiplied by its interval factor. Based on…
