Neira Torres, I, Gilles, G, Tchuindjang, J. T, Lecomte-Beckers, J, Sinnaeve, M, & Habraken, A. (2013). Prediction of residual stresses by FE simulations on bimetallic work rolls during cooling. Computer Methods in Materials Science, 13(1), 84-91.
Bimetallic rolls used in the roughing stands of the Hot Strip Mill require mixed properties as a high wear resistance for the shell material and an enhanced toughness for the core material. The bimetallic roll ...
Tuninetti Vásquez, V, Gilles, G, Péron-Lührs, V, & Habraken, A. (2012). Compression test for metal characterization using digital image correlation and inverse modeling. Procedia IUTAM.
In the case of sheet metal characterization, compression tests at normal direction of the sheet can be done by means of the layer compression test. Circular cylinder specimens are commonly used for compression ...
