Damage parameters of lamellar grey cast iron in tension

  • A. Fontaine
  • G. Zambelli


The tensile rupture behaviour of lamellar grey cast iron depends on the overall damage process of the heterogeneous microstructure. It is therefore of interest to apply the “continuum damage mechanics” concept to this type of material. Two parameters are considered: firstly the damage limit,σ0, and the damage rate,B. Measurements made on a grey cast iron, cast in three different cross-sections, show that these damage parameters may be used to separate the graphite network effects from those of the matrix which interact in the degradation process of the heterogeneous microstructure of lamellar grey cast iron.
