In the past few years, laser powder-bed fusion (LPBF) of bulk metallic glasses (BMGs) has gained significant interest because of the high heating and cooling rates inherent to the process, providing the means to bypass the crystallization threshold. In thi ...
The viscoelastic behavior of dilute suspensions of reduced graphene oxide (RGO) nanoparticles in a liquid SU8 epoxy dissolved in gamma butyrolactone was investigated at RGO concentrations in the range from 0.16 to 1.07 vol. %. Our results revealed that the ...
One of the most instrumental aspects governing the response of structural concrete at ultimate limit state refers to the possibility of developing smeared cracking patterns within a member (associated normally to the presence of sufficient reinforcement fo ...
Understanding the mechanical behavior of soft materials is of great importance for many applica-tions, especially for bioengineering and clinical applications. Hertzian theory is frequently used to characterize the mechanical properties of such materials. ...
Tribology properties emerge from a variety of mechanisms occurring along the sliding surfaces, at different length scales and time scales. Engineering friction and wear laws are mostly empirical, fitted against experimental results and thus only valid on a ...
Strengthening by needle-shaped precipitates is critical in Al–Mg–Si alloys. Here, the strengthening is studied computationally at the peak-aged condition where precipitate shearing and Orowan looping are usually considered to have equal strengths. Pseudo-r ...
Nowadays the use of natural fiber composites has gained significant interest due to their low density, high availability, and low cost. The present study explores the development of sustainable 3D printing filaments based on rice husk (RH), an agricultura ...
Structural steels have long been used in construction applications. Their mechanical properties and behavior under seismic loading or under fatigue design are of considerable interest for researchers and engineers. Although extensive studies have been cond ...
Parameters influencing tensile testing of bulk structural adhesives have been investigated to better understand tab failures, fracture shapes and high-frequency fatigue testing. Dumbbell molded structural adhesive specimens with tapered aluminum tabs have ...
In infinite dimensions, many-body systems of pairwise interacting particles provide exact analytical benchmarks for the features of amorphous materials, such as the stress--strain curve of glasses under quasistatic shear. Here, instead of global shear, we ...
