Paper Abstract

Ductile cast iron containers for transportation and deposition of radioactive waste have to be designed carefully in order to avoid unacceptable damages and leakages in case of an accident. Therefore various calculation and experimental methods are used during development and licensing of the containers. Besides others the container has to suffer severe impacts (e.g. falling from a height of several meters onto a concrete base). The level of strains must not exceed a value which would adversely affect the package in such a way that it would fail to meet the applicable requirements. In practice complex events as an impact are very difficult to calculate. Both the position of maximum stress and the time of its occurrence are not easy to be predicted with conventional methods. Therefore holography as an integral measuring technique was combined with strain gauge techniques and FEM calculations to analyze the integral and local loads of the container at drop tests. In this paper we explain the experimental and analytical proceedings and the combination of the results.
