Energy-Consistent CoRotational Schemes for Frictional Contact Problems
نویسندگان
چکیده
In this paper, we consider the unilateral frictional contact problem of a hyperelastic body in the case of large displacements and small strains. In order to retain the linear elasticity framework, we decompose the deformation into a large global rotation and a small elastic displacement. This co-rotational approach is combined with a primal-dual active set strategy to tackle the contact problem. The resulting algorithm preserves both energy and angular momentum.

Energy-Conserving Algorithms for a Corotational Formulation
Standard nonlinear schemes for the the simulation of elastodynamic problems have several shortcomings when considering high-speed rotations. To tackle these problems, we use a corotational framework and a corresponding specific linearization to design new energy-conserving numerical schemes. In the two-dimensional case, an algorithm preserving also angular momentum is presented. The existence o...
متن کاملDual Weighted Residual Error Control for Frictional Contact Problems
In this paper goal-oriented error control based on dual weighted residual error estimations (DWR) is applied to frictional contact problems. A mixed formulation of the contact problem is used to derive a discretization. It relies on the introduction of Lagrange multipliers to capture the frictional contact conditions. The discretization error is estimated in terms of functionals (the quantities...
متن کاملAn Efficient Implicit Scheme for the Treatment of Frictional Contact between Deformable Bodies
Newly interpolated implicit schemes are presented for the transient response of highly nonlinear problems of large deformation analysis presenting important material dissipation. Surprisingly these schemes exhibit excellent convergence properties that make them a cost efficient alternative to explicit schemes generally advocated as the best choice for these problems. Three problems of dynamical...
متن کاملNumerical Analysis of a Nonlinear Evolutionary System with Applications in Viscoplasticity
We consider numerical approximations of a class of abstract nonlinear evolutionary systems arising in the study of quasistatic frictional contact problems for elastic-viscoplastic materials. Both spatially semi-discrete and fully discrete schemes are analyzed with the nite element method employed to discretize the spatial domain. Strong convergence of both approximations is established under mi...
متن کاملIsogeometric Analysis Applied to Nonlinear Elastodynamics
A numerical investigation is carried out in this work in order to evaluate the computational performance of a numerical model based on isogeometric analysis for applications on geometrically nonlinear elastodynamics. In the FEM (finite element method) practice, it is well known that the Newmark’s method is unconditionally stable for linear structural systems, but this characteristic is frequent...
