- Cardiff’s exact strip software provides an accurate, efficient alternative to finite element analysis and has been used by Airbus to achieve weight savings in the A320 NEO aircraft family, as corroborated by the Vice President, Engineering. However, exact strip analysis is restricted to prismatic plate structures, precluding the modelling of localised damage such as delamination in composites. This work removes this restriction through a hybrid approach, combining the efficiency of exact strip analysis in the undamaged parts of the structure with the versatility of finite element analysis in the damaged regions, leading to a wider range of aerospace design applications.
