Abstract

The stress calculated method of isogeometric structure analysis is studied in this paper. Based on the fact that stress calculated values at Guass integral points are more accurate than other locations, the stress field can be rebuilt by fitting the Guass integral point’s stress value from the displacement field, and two methods including stress interpolation and least square fit are presented to reduce the stress error. The example of infinite plate with circular hole is used to illustrate our methods’ performance, and the results show that our methods can improve the stress calculate accuracy notable.
