Study and Application of High Precision Nonlinear Plane Stress Element[J]. Journal of Civil and Environmental Engineering, 2007, 29(3): 83-87. DOI: 10.11835/j.issn.1674-4764.2007.03.020.
A tangent stiffness matrix for quadrilateral plane stress element under large rotation with small strain is proposed in this paper
The corresponding program based on this theory has been worked out;The computation of examples with analytic values has verified that the element's formulation
its program given in this paper have strong nonlinear computation ability;A nonlinear whole-course analysis of stone arch bridge has been done in this paper.The computations presented preferably a comprehensive understanding of nonlinear characteristics of stone arch bridge with small span and could be beneficial for the engineer designers.
