has undergone continual technological advancements to improve machining efficiency. However, the sustainability of this process is gaining heightened attention due to significant challenges associated with the substantial specific grinding energy and the extensive heat generated when working with difficult-to-cu...
During FSW process, the material undergoes intense plastic deformation at elevated temperature, resulting in the generation of fine and equiaxed recrystallized grains [1]. The fine microstructure in friction stir welds produces good mechanical properties. Due to the solid-state nature, FSW has some ad...
Rheological and differential scanning calorimetry measurements on EPS aqueous dispersions indicate the formation of an extended 3-D network above a threshold concentration, with a clear dependence of the mechanical and water retention properties on EPS content. The structural characterization, performed with...

Flow characteristics – concept of control volume - application of ...
The surface and deformation analyses of the interface are then considered in Chapter 3; these lead to the theoretical expressions, as functions of the contact pressure, the properties of the materials and the surfaces, for the solid spot conductance of a joint consisting several contact spots. ...
directed toward thermoplastic vulcanizates that include a propylene-based polymer and a butene-1-based polymer in the plastic phase; the presence of both the propylene-based polymer and the butene-1 based polymer provides for thermoplastic vulcanizates characterized by advantageous mechanical properties. ...
Different types of MR fluids exhibit particular characteristics according to their rheological properties. The MR fluid used in this study is MRF-140CG, which was acquired from the Lord Corporation. The MR brake structure determines the direction of the magnetic field lines. To achieve torques with...
These findings highlight the clear economic benefits of adopting cellular solid materials in civil engineering, not only in terms of improved energy efficiency but also in terms of significant reductions in material expenditures. Mechanical properties of cellular materials, such as honeycombs, foams, or...
