Simulation of Residual Stress and Distortion on Additively Manufactured SS316L Specimens Using Inherent Strain Method

Simulation of Residual Stress and Distortion on Additively Manufactured SS316L Specimens Using Inherent Strain Method

This paper presents the application of inherent strain method (ISM) for predicting distortion on selective laser melting (SLM) specimens using general purposed finite element method (FEM) software. Since the prediction distortion might acquire extensive computational time, direct analytical approach...

This paper presents the application of inherent strain method (ISM) for predicting distortion on selective laser melting (SLM) specimens using general purposed finite element method (FEM) software. Since the prediction distortion might acquire extensive computational time, direct analytical approach is applied as an alternative to other method such as thermo-mechanical method. The procedure will start with the estimation of initial inherent strain value based on process parameters and material properties of austenitic stainless steel SS316L as well as the effective area. The selected SLM parameters are laser power, beam spot diameter and efficiency, along with material properties. It is to be expected, that the simulation outcome of simplified geometry with general purposed numerical software, MSC Marc/Mentat 2019 will exhibit acceptable estimation compared to specialized additive manufacturing software. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
