Residual Stress and deformation analysis and prediction of SLM manufacturedsamples with the Inherent Strain method

The residual stress developed during manufacturingprocesses has an important role on the success of the samplesmanufacturing. The laser powder bed fusion method ofadditive manufacturing has been widely used in differentindustries to produce prototypes as well as the geometricalcomplex parts. Prediction of the residual stress of the samplesis an important challenge for these parts. The inherent strainis used in the present research to simulate the manufacturingmethod to fabricate the tensile test samples. The numericallymanufactured sample is tested and the obtained stress-straincurve is compared with the experimental results
