AbstractThe development of new methods in analysing package designs using the finite-element method is of increasing importance. Package designers are increasingly applying the growing opportunities afforded by numerical methods to perform safety assessments for their products; this also requires suitable methods for competent authorities like BAM to verify applicants' results. This paper gives a topical overview of experiences and trends within the complex field of finite-element design testing. First some general and more formal aspects are described concerning the selection of the correct finite-element program and documentation of modelling, material properties, boundaries and calculation results, including their interpretation. To give a reliable basis for applicants in Germany BAM has recently drawn up and published a Finite Element Guideline. Secondly, actual technical questions are discussed: these are of wide interest and range from mechanical reflections on cask drop and extreme impact scenarios...
