Sensitivity analysis in the modelling of a high speed steel thin-wall produced by directed energy deposition
RT Jardin, V Tuninetti, JT Tchuindjang, N Hashemi… - Metals, 2020 - mdpi.com
This paper reports the sensitivity of the thermal and the displacement histories predicted by
a finite element analysis to material properties and boundary conditions of a directed-energy
deposition of a M4 high speed steel thin-wall part additively manufactured on a 42CrMo4
steel substrate. The model accuracy was assessed by comparing the simulation results with
the experimental measurements such as evolving local temperatures and distortion of the
substrate. The numerical results of thermal history were successfully correlated with the …
