Implementation of a gradient-enhanced damage law

The aim of your work will be the extension of an existing material model developed at the IKV by a suitable method of regularization (gradient-enhanced).

Crash - energy absorption by FRP
Based on their excellent weight-specific properties and high energy absorption capacity, fibre reinforced plastics are an ideal material for highly dynamically loaded structures. An important component is the numerical modelling of the damage behaviour of the constituents. In order to guarantee an objective consideration of the results, the use of regularization methods is unavoidable.

The aim of your work will be the extension of an existing material model developed at the IKV by a suitable method of regularization and the optimization of the material model in terms of computing time. The implementation of the regularization method will be performed with the structure simulation tool Abaqus.

During your thesis you will gain experience in the following areas:

  • Understanding the numerical modelling of FVK on the micro level
  • Insight into damage laws and deep understanding of non-local gradient enhanced regularisation
  • Deep understanding of Abaqus

If you are interested, just contact me! Your tasks and the timeframe will be determined together according to your final thesis.
We offer you an exciting and highly relevant topic for both industry and research. The highly motivated working group will support you and make it easier for you to work on your thesis.
