摘要

The hole-drilling method for residual stress is widely used and theoretically elaborated. The Integral Method, which is considered to be the most important and fundamental theory, is based on a calibration carried out by Finite-Element-Analyses. This paper describes some finite element calculations which provide coefficients needed for successful general applications. A new different finite element approach is considered by the authors. And a more efficient and more comprehensive application finite element calculation procedure using the General Axisymmetric Elements is described below. Different from the Harmonic Axisymmetric Elements restricted to linear materials and sinusoidal loading, the General Axisymmetric Elements support any type of material and loading, including geometric nonlinear analyses. Compared with an equivalent 3-D model, the general axisymmtric model greatly reduces the modeling and analysis time. Thus a new model between 2-D and 3-D is proposed in this work to further improve the shortcomings described above. Through this new method, the analysis is extended to the residual stress measurement of relatively thin plate and the range of thin plate is redefined.
