Abstract
Modern exhaust systems must withstand servere cyclic mechanical and thermal loads throughout the whole life cycle. Growing demands on designs targeted at reliability and cost optimization require new methods in lifetime prediction. Presently, highly loaded parts like exhaust manifolds are predominantly designed experimentally by means of lengthy and expensive component tests. Further shortening of development time without quality loss is possible only by increasing the application of computer simulation.
