Experimental study with a Digital Image Correlation (DIC) method and numerical simulation of an anisotropic elastic-plastic commercially pure titanium

In this paper, the tensile behaviour of a commercially pure titanium is studied using a full-field strain measurement. A fine analysis of the measured strain fields is carried out in order to determine the intrinsic behaviour of the material. An elastic-plastic model taking material anisotropy into...

Description
Summary:In this paper, the tensile behaviour of a commercially pure titanium is studied using a full-field strain measurement. A fine analysis of the measured strain fields is carried out in order to determine the intrinsic behaviour of the material. An elastic-plastic model taking material anisotropy into account is proposed. On the basis of experimental results, the parameters of this model are identified then introduced into a FEM code in order to simulate the behaviour of titanium. To assess the performance of the approach, the numerical results are finally analysed and compared with measurements coming from image processing. A quite satisfactory agreement between simulation and experiment is obtained.
