A Probabilistic Approach in Failure Modelling of Aluminium High Pressure Die-Castings

Knoll, Octavian

Abstract:
Aluminium high pressure die-castings are essential elements of a modern car body, e.g. structural nodes are produced as die-castings. Numerical models are required to guarantee structural reliability. However, the ductility of die-castings is influenced by defects caused by the casting process. As a result, the ductility exhibits a global systematic variation and a local random variation. The main objective of the present work is the experimental and numerical analysis of these variations.
