Summary of the master project:
Sequential linear analysis is a new simulation approach for analysis of mechanical
behavior of brittle structures which is based on finite-element analysis. Where in the
traditional iterative incremental approaches a consistent configuration is searched
with predefined load-increments, in the sequential linear analysis the damage is
incremented. A practical advantage of sequential linear analysis is that it is very
robust and can handle very brittle behavior of structures. In the sequential linear
approach a large set of linear equations must be solved repetitively, where each time
the matrix is changed only locally. In the present implementation in the DIANA
software every time the full matrix is inverted, which is very inefficient. The project
will focus on the question how to reduce the analysis time for sequential linear
analysis.
