Introduction The development of nickel-based superalloys in the past few decades has been driven by ever increasing requirements of materials for gas turbine in modern civil jet engines.
The Materials Genome Initiative (MGI) and Integrated Computational Materials Engineering (ICME) are recently introduced as the new approach.
They were transformed in either engineering stress-strain curves or engineering resolved shear stress-strain curves from the initial length and upper diameter of the pillar and the initial length and upper diameter of the pillar and the initial Schmid factor calculated from the crystallographic orientation of the pillar.

To evaluate the impact of dune sand and lime addition on the mechanical behavior of bituminous mixtures containing high rates of RAP, complex modulus tests were conducted on the studied mixtures, at different temperatures and frequencies, using a two-point bending device that was developed at the National School of Engineers of Tunis.
Experimental methods To determine the complex modulus of the bitumen mixtures, an experimental 2-point bending test setup, shown in Fig. 5 has been developed at the National School of Engineers of Tunis, in compliance with the French standard (EN 12697-26).
