Object-oriented non-linear finite element analysis: Application to J2 plasticity

摘要: Abstract The object-oriented programming concept is applied to the finite element method for non-linear static analysis. Starting from an existing linear environment, question whether approach can be suitably extended situations where algorithmic procedure dominant examined. Newton-Raphson and stress-integration algorithms are presented along with necessary extensions objects. implementation in C+ + described. advantage of demonstrated, particular through non-anticipation state object.
