摘要：
A meshless shell method for dynamic fracture problems based on normalized smoothed particle hydrodynamics (SPH) is presented. The SPH method is corrected by a normalization in order to fulfill completeness requirement. Instabilities are controlled by stress-point integration. The method is modified for Mindlin-Reissner shell analysis. Stress based fracture criterion is incorporated based on the visibility method. The method is applied to two dynamic fracture problems. Results are very promising. (C) 2009 Elsevier Ltd. All rights reserved.
