摘要
The paper has successfully applied co-rotational procedure to derive non-linear tangent stiffness matrix of Triangular Plane Element in large but small-strained displacement. Interestingly, this tangent stiffness matrix is asymmetric, and a non-linear finite element iteration procedure is also established by the Newton-Raphson technique, and a corresponding FORTRAN program NTTP completed. a case study on a beam structure verified the effectiveness of the matrices for structural geometric nonlinear analysis.
