Motivation:
-
Consideration of residual stresses due to the manufacturing process; parareal time integration for the treatment of long-term problems (e.g. high number of cycles)
Objective:
-
Development of a material model and efficient time integration methods for thermomechanically loaded corrugated components using the finite element method
Solution approach:
-
Experiment: Quasi-static tension-torsion experiments
-
Theory: Material model development/identification (cyclic thermoviscoplasticity, residual strain, anisotropy, initial defects)
-
Numerics: time-adaptive integration methods of higher integration order (SDIRK, PRK, BDF method for large DAE systems); FCM to take surface waviness into account
