REAL-TIME COMPUTATION OF ELEMENT STIFFNESS MATRIX BASED ON BP NEURAL NETWORKS

Elastoplasticity 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. T he 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. DOI: http://dx.doi.org/10.5755/j01.mech.18.1.1279
