Identification of fracture parameters for dense concrete by means of neuro-fuzzy system anfis

摘要

The Adaptive Neuro-Fuzzy Inference System (ANFIS) is applied toidentification of relationship between the values of water-cementratio (W/C) and the parameters of fracture mechanics according toMode II of dense concrete (K_IIC, J_IIC). Regular division of inputspace and "bell" membership function were adopted in the system. Theresults were compared with the polynomial approximation.
