The use of stress simulation in casting design and manufacturer has found
wide spread use in not only the automotive industry but also more general
engineering castings. The development of light-weight body structures in
the automotive industry has lead to a new generation of large thin walled
complex aluminium and magnesium castings with demanding dimensional
and stiffness tolerances, which require particular attention to casting
design and production techniques. To achieve economic production long
die tool life is required and thermo mechanical fatigue cracking ‘heat
checking’ is often the limiting factor. Minimum distortion and maximised die
life can be achieved by using simulation tools and optimisation techniques
during casting design and production. A group of companies with
competences in casting simulation, material testing, design and high
pressure die casting has worked together on the overall design and
manufacturing process and examples will show the success of this
approach. The paper will give a review of the current capabilities of the
application of a numerical simulation to stress related problems in casting
manufacture.
