Behaviour model identification based on inverse modeling and using Optical Full Field Measurements (OFFM): application on rubber and steel
Abstract
Biaxial properties of materials (polymer or steel) used in many industrial processes are often difficult to measure. However, these properties are useful for the numerical simulations of plastic-processing operations like blow moulding or thermoforming for polymers and superplastic forming or single point incremental forming for steels. Today, Optical Full Field Measurements (OFFM) are promising tools for experimental analysis of materials. Indeed, they are able to provide a very large amount of data (displacement or strain) spatially distributed. In this paper, a mixed numerical and experimental investigation is proposed in order to identify multi-axial constitutive behaviour models. The procedure is applied on two different materials commonly used in forming processes: polymer (rubber in this first approach) and steel. Experimental tests are performed on various rubber and steel structural specimens (notched and open-hole plate samples) in order to generate heterogeneous displacement field. Two different behaviour models are considered. On the one hand, a Money-Rivlin hyperelastic law is investigated to describe the high levels of strain induced in tensile test performed on a rubber open-hole specimen. On the other hand, Ramberg-Osgood law allows to reproduce elasto-plastic behaviour of steel on a specimen that induces heterogeneous strain fields. Each parameter identification is based on a same Finite Element Model Updated (FEMU) procedure which consists in comparing results provided by the numerical simulation (ABAQUS (TM)) with full field measurements obtained by the DISC (Digital Image Stereo-Correlation) technique (Vic-3D (R)).
