Abstract : Using the modern computerized analysis, the special purpose computer program SLOOFSAN can be successfully applied for the evaluation if thin structure strength limits in presence of extreme dynamic loading phenomena. This program correctly solves wave-propagation-type of problems involving short transient (very rapid loading-time sequence) and including shock-wave response from impulsive loading (explosion or blast wave) and impact loading (missile impact). SLOOFSAN program is based on a finite element shell formulation using the Semiloof element and has been developed for transient dynamic non-linear analysis applying an efficient explicit direct time integration technique. SLOOFSAN 3-D capabilities in the fields of structural safety assessment and anti-missile design are illustrated in the paper. (Author)
