4. (4 ) because calculation of stress intensity factors using the finite element method of the linear elastic fracture mechanics cannot satisfy the need for the real-time monitoring and the real-time analysis of cracks in concrete dams, a four-layer neural network optimized by genetic algorithm and chaos optimization algorithm is proposed . the example shows that the optimized neural network can yield good results
   (4)用斷裂力學有限元計算應力強度因子不能滿足對混凝土壩裂縫實時監(jiān)測、實時分析中的要求，提出了利用遺傳算法和混沌優(yōu)化算法改進的四層神經網絡的解決方法，實例分析表明，本文提出的四層優(yōu)化神經網絡計算的應力強度因子接近于用斷裂力學有限元計算的應力強度因子。
5. a general consensus exists related to the influence of slow crack propagation ahead of the crack tip upon the nonlinearity observed in the typical load-deflection response of the concrete specimen, namely, concrete exhibits somewhat quasibrittle behavior, which has been verified by the inapplicability of the conventional linear elastic fracture mechanics ( lefm ) and fracture models suitable for metal-like materials
   現(xiàn)在已經意識到，混凝土在其典型的位移曲線中呈現(xiàn)出的非線性特征是由于裂縫在端部的緩慢擴展引起的，可以認為是混凝土的一種半脆性性能。這是在發(fā)現(xiàn)傳統(tǒng)的線彈性斷裂力學(lefm)和適合金屬類材料的斷裂模型不適用于混凝土研究時得出的結論。
