- Abstract
- In situ tensile tests were carried out during X-ray microtomography imaging of three steels: a single phase ferritic steel, a dual phase steel and a fully martensitic steel. Cavity growth was first quantified in the different samples as a function of strain and triaxiality. The Rice and Tracey model, a version of this model corrected by Huang, and a third version accounting for the cavity shape were then used to predict void growth evolution. It was experimentally demonstrated that for steels Huang’s correction is a real improvement to the original Rice and Tracey model. Some differences in the void growth kinetic are discussed, accounting for the microstructure and the mechanical behavior of each steel.
