Abstract Nonlinear behaviors are commonplace in many complex engineering
applications, e.g., metal forming, vehicle crash test and so on. This paper focuses
on the T-spline based isogeometric analysis of two-dimensional nonlinear problems including general large deformation hyperelastic problems and small deformation elastoplastic problems, to reveal the advantages of local refinement
property of T-splines in describing nonlinear behavior of materials. By applying
the adaptive refinement capability of T-splines during the iteration process of analysis, the numerical simulation accuracy of the nonlinear model could be
increased dramatically. The Bézier extraction of the T-splines provides an element
