Abstract

A low-cycle thermal fatigue test at heat shock is carried out on a simple specimen of cast iron, as the material of cylinder head.Meanwhile a finite element (FE) model for specimen is built and a FE simulation on the temperature, stress and strain fields of specimen is conducted with the fatigue life of the specimen predicted. The fatigue life predicted well agrees with test result, indicating the correctness of the model built and the simulation scheme used. The low-cycle thermal fatigue damage of cylinder head has a certain similarity to that of cast iron specimen, so the test and simulation methods used in the paper are also suitable for the study on the thermal fatigue life of real cylinder head.
