WCCM2018: Mini-Symposium ID: 225 "MODELLING OF MICROSTRUCTURE-DEPENDENT DAMAGE AND FRACTURE OF HETEROGENEOUS MATERIALS"

Dear Colleagues,

We cordially invite you to present your research work at the mini-symposium – “MODELLING OF MICROSTRUCTURE-DEPENDENT DAMAGE AND FRACTURE OF HETEROGENEOUS MATERIALS” at the 13th World Congress on Computational Mechanics (New York City, from July 22 to 27 of 2018). The session ID is 225 (Link: http://www.wccm2018.org/MS_225).

Submission deadline: December 31, 2017. Session description is given below. We look forward to your contribution in this min-symposium.

Best regards

MR Kabir, Material research Institute, German Aerospace Center, Cologne, Germany.

Session Description:

This minisymposium concentrates on current and advanced computational approaches of microstructure-dependent damage and fracture modelling of heterogeneous materials. The focus will be on efficient and novel modelling techniques, which incorporate microstructural effects on single or multiple microstructural length scales. Such techniques are currently applied to improve the understanding of fracture process, damage evolution and material degradation in complex material systems as well as to correlate the damaged microstructure to the structural failure of components. The loading can be mechanical, thermal, or any other degenerating condition, even multi-physical loading conditions can be investigated.

Modelling techniques may include scale bridging concepts, homogenization methodologies for damaged microstructure cells, and advanced constitutive damage modelling incorporating microstructure sensitivity, applying Atomistic, Molecular dynamic, Phase Field, Finite and/or Discrete Element Methods. In particular, abstracts containing the coupling of these (or other) models are encouraged, since any scale bridging in combination with microstructure-base damage models is still a challenge.

Materials with hierarchical microstructures, such as, but not limited to, polycrystals, composites, granular or biological materials will be covered. Dynamic fracture problems for practical applications where microstructural arrangements crucially influence material failure behaviour are also within the scope of the symposium. Advanced experimental techniques (Nanoindentation, Digital Image Correlation, etc.) that can be used to validate numerical models and that give insight into the microstructural role on damage formation are also welcome, particularly in combination with these models. Based on the above topics, the goal of this mini-symposium is to bring together researchers from various disciplines to discuss current issues on the fracture and damage modelling incorporating complex microstructural aspects that are essential for a reliable prediction of damage and fracture behaviour of heterogeneous materials.
