Abstract
This research investigates the evolution of plastic strain-induced damage and martensite transformation at ambient temperature in austenitic stainless steels AISI-316. A constitutive model is developed within the Continuum Damage Mechanics framework to account for strain-induced phase transformation and damage growth during plastic deformation. This model is implemented using the UMAT subroutine in ABAQUS/STANDARD for numerical simulations. Experimental tests, including tensile and torsional tests with loading-unloading, have been conducted to assess the damage. X-ray diffraction has been used to measure the volume fraction of martensite. This 3D model accurately predicts the hardening behavior, martensite evolution, and damage growth at room temperature. Simulation results and experimental data have been compared for verification purposes.
