Affine conjugate adaptive Newton methods for nonlinear elastomechanics

Zitieren Sie bitte immer diese URN: urn:nbn:de:0297-zib-7768
  • The paper extends affine conjugate Newton methods from convex to nonconvex minimization, with particular emphasis on PDE problems originating from compressible hyperelasticity. Based on well-known schemes from finite dimensional nonlinear optimization, three different algorithmic variants are worked out in a function space setting, which permits an adaptive multilevel finite element implementation. These algorithms are tested on two well-known 3D test problems and a real-life example from surgical operation planning.
