摘要
通过人工神经网络方法构建砂砾石材料的非线性本构模型,结合工程实例进行了有限元分析计算,提出了对有一定高度的同性材料按不同围压进行分区,并结合神经网络本构模型进行计算的方法;研究结论对神经网络在本构模型上应用的特点提出了基本的研究思路.
In this paper,by artificial neural network,nonlinear constitutive models of sand and gravel materials was constructed,with engineering examples and the finite element analysis and calculation.We gave the method made on a certain high level of homosexual material in different partition confining pressure,combined with neural network constitutive model calculation.The research gives the basic research ideas on the characteristics of the neural network constitutive model in application.
