Abstract
The elasto-viscoplastic-creep constitutive equation based on the concept of continuum damage mechanics is formulated for the gray cast iron as used in diesel engine parts. Lots of material parameters in the constitutive equation are determined by using the uniaxial tensile/compressive, the creep, the stress relaxation and the fatigue test results. The identified model is applied to the creep fatigue life prediction of a cylinder head used in diesel engine parts which is made of gray cast iron. The part 1 describes the identification of the damage model based on the material test results for the gray cast iron. [This abstract is not included in the PDF]
