The so-called T-stress, or second term of the William (1957) series expansion for linear elastic crack-tip fields, has found many uses in fracture mechanics applications. In this paper, an interaction integral method for calculating the T-stress for two-dimensional crack problems using the extended radial point interpolation method (XRPIM) is presented. Typical advantages of RPIM shape function are the satisfactions of the Kronecker’s delta property and the high-order continuity. The T-stress can be calculated directly from a path independent interaction integral entirely based on the J-integral by simply the auxiliary field. Several benchmark examples in 2D crack problem are performed and compared with other existing solutions to illustrate the correction of the presented approach.

To help process design silo containing wheat, rice more effectively meet the urgent demand of the system stockpiles, this paper built a program calculations, tests strength, aims to optimize the design of silo. This program combines powerful computing capabilities of ANSYS in finite element method and the ability to design intuitive interface of Visual Basic. The authors proposed a process for calculating the silo as round and square form of the Long An Machinery Industry Joint - Stock Company (LAMICO) and realize the software calculates silo CCMSilo.
