ESR 14:
Geometrically and materially nonlinear beam dynamics with strain localisation

Description

The ESR will work on numerical modelling of flexible beam-like structures with a special focus on strain localization. In damaged materials, strain localisation often occurs, resulting in discontinuity of strains in structural models and local loss of uniqueness of the solution. This makes the problem challenging and special solution methods need to be designed to be capable of dealing with such phenomena. We are looking for stable, reliable and numerically efficient methods for frame-like structures.

Expected Results

A novel family of finite beam elements taking into account geometrical and material non-linearity that will be able to describe strain localisation will be proposed. Open-source software capable of efficiently solving spatial frame-like structures with strain localization is expected to be developed.
