Failure load predictions of composite structures during fire
2007 (English)Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

Fire response simulations on composite materials gets increasingly important, as the materials are used for load carrying structures, such as in military and commercial ships. Real life fire tests are expensive and classifying a new material for usage can be costly. A methodology has been derived for designing composite structures for fire safety. Fire simulation software such as Com Fire and Csp Fire as well as the FE-software Ansys have been tested and validated. The simulation software proved to have severe stability issues and could not be used to get trustworthy simulation results. It was also shown that the effects of the material degradation were negligible and hence only thermo-mechanical simulations were used in the methodology. Also an Excel tool has been created to perform simplified failure load predictions.
