| Abstract: | A set of basic equations of mapping-collocation techniques were introduced for limited plane region with an internal hole. Taking rectangle plates with a central crack as examples, the influence of various computation factors on the results of the geometric correction factor YI of mode I stress intensity factors (SIF) were studied computationally. Through a lot of computational research, a reasonable computation scheme was established for mappingcollocation techniques. Some curves or tables of the geometric correction factor YI vs various computation factors were showed in this paper. |
