Article: A state-of-the-art review on all constitutive models in simulating mechanical behaviour of metals and alloys Journal: International Journal of Materials Engineering Innovation (IJMATEI) 2021 Vol.12 No.4 pp.337 - 363 Abstract: The motivation for the current paper is derived from the drawbacks of all the physical mechanical tests such as tensile, hardness and impact tests that are widely employed for predicting and improving the functionalities and performance of the industrial components in their service life phase. These tests are time consuming, costly and lack analytical understanding of the material behaviour. A virtual mechanical test simulation provides an alternative approach for enhancing sustainability and explaining comprehensively the mechanical behaviour of various metals and alloys by exploiting the recent analytical and semi empirical constitutive models. In this paper, the feasibility of the models associated with the determination of tensile, hardness and impact properties have been studied in three different sections. The outcome of the study is the clarity in choosing the most feasible models, role of the various parameters associated with these models in defining the behaviour of materials, role of the correction factors (adjusting the predicted and measured values) and identification of the model input-output parameters with the future intention of implementing these models in the virtual material testing framework.

Abstract: The motivation for the current paper is derived from the drawbacks of all the physical mechanical tests such as tensile, hardness and impact tests that are widely employed for predicting and improving the functionalities and performance of the industrial components in their service life phase. These tests are time consuming, costly and lack analytical understanding of the material behaviour. A virtual mechanical test simulation provides an alternative approach for enhancing sustainability and explaining comprehensively the mechanical behaviour of various metals and alloys by exploiting the recent analytical and semi empirical constitutive models. In this paper, the feasibility of the models associated with the determination of tensile, hardness and impact properties have been studied in three different sections. The outcome of the study is the clarity in choosing the most feasible models, role of the various parameters associated with these models in defining the behaviour of materials, role of the correction factors (adjusting the predicted and measured values) and identification of the model input-output parameters with the future intention of implementing these models in the virtual material testing framework.
