Modeling Thermomechanical Stress with H13 Tool Steel Material Response for Rolling Die under Hot Milling
Tolcha, Mesay Alemu; Lemu, Hirpa G. (Peer reviewed; Journal article, 2019)For the extreme pressure and temperature arising in the hot rolling process, thermomechanical (TM) models are used to predict the residual stresses on the surface of the die because a quantification of the TM stresses ... -
Utilizing multiple criteria decision-making optimization methods to machine LM25Al/VC material under electro-discharge machining processes
Tolcha, Mesay Alemu; Lemu, Hirpa G. (Peer reviewed; Journal article, 2023)In this work, sparking electro-discharge machining (EDM) process parameters are optimized by using multiple criteria decision-making (MCDM) methods. The work piece utilized for the investigation was LM25 aluminum alloy ...
