Engaged for many years in research work concerning the safety and inte
grity of nuclear containments, the first author has performed numerous
theoretical and experimental investigations at this institute. Airpla
ne crashes on nuclear power plants, as well as containment attacks by
detonation and missiles generated by bursting vessels have been studie
d with respect to practical design. Also, a series of fundamental rese
arches has been done to evaluate constitutive laws for shockwaves in c
oncrete and constitutive relations for concrete with regard to strain
rate effects. Further investigations have focused on friction phenomen
a for projectiles impinging on concrete.
