Determination of material properties using dynamic tests supported by thermography, digital image correlation and numerical simulation
Presented research is based on comparing experimental methodology, based on the middle wave infrared thermography and the digital image correlation, with constitutive modeling and numerical simulation of aluminium alloy deformation process. Digital image correlation is used as a comparison tool to the novel infrared approach of tracing plastification and damage process in material. Knowledge obtained from dynamical experiments at lower velocities is used as a basis for evaluating impact where infrared approach enables acquisition of plastification and damage at higher frame rates. Examples include evaluation of tension and three point bending aluminum alloy specimens tested at different strain rates. Obtained strain and temperature distributions are used as input for the calibration of material parameters in constitutive relations. The computational model accuracy is verified by excellent agreement with experimental measurements
