Additionally, the mechanical properties of HSC were considerably enhanced by applying 5.23 MPa pressure over 8 h. It is worth mentioning that the bonding strength between HSRM and substrate HSC without curing was highly affected by the duration of pressure application compared to the three investigated curing methods.

It is widely accepted that the mechanical behavior of rock is highly dependent on the properties of the minerals within the rock (Li et al., 2021b, Li et al., 2021c). An increasing amount of attention has been given to validating the relationship between rock mechanical properties and mineral composition.

However, the van der Waals forces between CNTs make them highly susceptible to agglomeration [17], significantly limiting the efficiency of reinforcing the mechanical and tribological properties of rubber composites. Given this problem, some researchers have begun to functionalize the surfaces of CNTs, which provides a new method for preparing ...

Correlation between the mechanical properties and each of the structural variables was calculated by Pearson's correlation coefficients (p<0.05). The flexural strength values ranged from 493 to 835 MPa and were directly correlated with the fiber/matrix ratio (p=0.011). The flexural modulus ranged from 4500 to 8824 MPa and was inversely ...

The significance and validity of the relationships between the mechanical properties and the final surface roughness values were interpreted using test statistics. It was found that there were statistically significant correlations between uniaxial compressive strength and tensile strength and the surface roughness of the studied marble specimens.

The mechanical and the anatomical axes of the tibia are almost identical. Both lines run parallel, whereby the anatomical tibial axis lies a few millimeters medial to the mechanical tibial axis. The mechanical axis of the leg (Mikulicz line) is the connecting line between the center of the femoral head and the center of the ankle joint .

The plate is manufactured from an elasto-plastic material; in the analysis presented here we assume full coupling between the mechanical and diffusion processes and make constitutive assumptions that are appropriate for a Nickel based alloy. The main reason for analysing this geometry is that it gives rise to a high degree of plastic constraint ...
