DyF: Dynamic Fracture
Minisymposium organized by
The minisymposium is dedicated to the simulation of dynamic crack propagation in all types of materials and structures and at all scales.
The effects of the loading rate are important in quasi-brittle materials, such as concrete. They exhibit dynamic response that strongly depends on the loading rate. With increase of the loading rate the resistance is increasing, failure mode is changing and there is a crack branching phenomena. At least that is what we observe in tests. We also know that with increasing loading rate the role of inertia increases at global as well as local level. It affects the stress distribution and the fracture process.
Recently there is renewed research interest in the dynamic fracture process. Many questions are still not fully answered especially on the topic of the true dynamic material response and how to take the local inertia effects into account.
There are a number of actual research questions such as: What is the effect of the loading rate on the fracture process at macro, meso and micro level? How can this process be modelled, what are the appropriate techniques? Is the rate dependency a material property represented in the constitutive model or is it due to local inertia that can be covered in detailed numerical simulations? How do we gain reliable data on the material response itself and the fracture process in tests? What diagnostic techniques should be applied? What is the role of moisture and porosity? Etc.
We invite authors to contribute to this session in order to share knowledge, exchange the results of different modelling approaches and compare these with experimental data.
Scale coupling and scale change, modes switch as well as comparison with experimental results are welcome. Moreover, the minisymposium also welcomes discussions of different approaches for the simulation of the same physical problem.
