REAL-TIME COMPUTATION OF ELEMENT STIFFNESS MATRIX BASED ON BP NEURAL NETWORKS
Keywords:element stiffness matrix, BP neural network
AbstractElastoplasticity computation is the analysis foundation of many complex mechanical behaviours such as fatigue, damage, and fracture. It is impossible to realize real-time computation of elastoplasticity based on serial computer. The form of the element stiffness matrix is analyzed. A method that may realize the real-time computation of element stiffness matrix based on BP neural networks is proposed. The element stiffness matrix is computed using finite element analysis and BP neural networks, respectively.
