Superior combinations of yield strength (YS), ductility (% El.), fracture toughness (Kee) and high cycle fatigue strength (σf) were obtained under certain conditions, i.e., i) MA steel: intercritical (α+γ) phase regime (~Ar1) controlled and 15-cycle multiaxially forged (MAFed) (YS=1027MPa, %El.=8.3%, σf=355MPa and Kee=90MPa√m), and ii) IF steel: ferritic region (El.=11.2%, σf=255MPa and Kee=97MPa√m).

The mechanism of GBS was examined by Majumdar et al. [8].
The 15-cycle MAFed MA steel specimens showed superior fracture toughness (Kee=90.0 MPa√m) along with high YS (1027 MPa) and good ductility (%El.=8.3).
In contrast, the best combination of YS (881 MPa), ductility (%El.=11.2) and fracture toughness (Kee=97.0MPa√m) was achieved for the 18-cycle MAFed IF steel samples.

UAM reduces the ability of chips to be stacked into the cutting edges [10] Bouncing back phenomena of CFRPs at the end of tool-workpiece engagement was reported by wang et.al [11].
Similar observation was described by wang et al. [11].

In this regard, Lee et al. reported in their study that the gauge factor of graphene film grown on Cu substrate by chemical vapor deposition (CVD) was 6.1 at 1% strain [5], though this value is still far beyond the target for highly sensitive sensor.
Meanwhile, Chen et al. reported that the gauge factor for graphene monolayer obtained by mechanical exfoliation method was 150 [2].
This value is higher than that prepared by Lee et al. using CVD, and provides a clear indication for the importance of utilizing graphene monolayer in the fraction process of strain gauge sensor.

Liu et al. [21] conducted experiments to evaluate the response of concrete containing rubber particles when subjected to cyclic loading.
In addition, Boukour et al. [20] conducted experimental research to examine how two waste materials could partially replace natural sand in a cement mortar.
In addition, this study uses two types of sand: the first is dune sand (DS) from the El Oued region, and the second is the alluvial sand (AS) from the Djamaa sand pit in El Oued Province.
