Research

Thermodynamic Topology and Materials Optimization
  • Development of variational approaches for the thermodynamic optimization of the topology of construction parts and engineering structures
  • Development of novel and numerically advantageous concepts for regularization to avoid the checkerboard phenomenon
  • Consideration of material and geometrical non-linearities as, e.g., fiber reinforced materials, hybrid materials systems (steel/concrete, 3D print), hyperelastic materials (rubber)

Stochastic Material Behavior

  • Development of novel approaches to modeling the stochastic behaior of elastic and inelastic materials, e.g., creep behavior in concrete, polymers, metals
  • Development of improved finite element formulations to accurately compute the local and global stochastic quantities as stress distribution and nodal forces
  • Generalized formulations

Damage Mechanics
  • Development of numerically advantageous regularization methods to avoid mesh dependencies in finite element simulations
  • Coupling of damage evolution to other microstructural processes as, e.g., plasticity, hardening, phase transformations
  • Consideration of thermo-mechanically coupled problems

Phase Transformations

  • Thermo-mechanically coupled material modeling of single-crystalline and poly-crystalline shape memory alloys including functional fatigue
  • Development of efficient simulation strategies for finite element computations of phase transformation inclduing plasticity
  • Thermodynamic analysis to determine universial material parameters
