A molecular dynamics simulation study on the interfacial strengthening between defected graphene and polypropylene matrix is implemented. As intrinsic defects in single layer graphene, oxidation, Thrower-Stone-Wales(TSW) defect, and Adatom defect are considered. On the transversely isotropic nanocomposites unit cell embedding different defected graphene, transversely isotropic stress-strain rel...

Structural hierarchy, porosity, and isotropy/anisotropy are highly relevant factors for mechanical properties and thereby the functionality of porous materials. However, even though anisotropic and hierarchically organized, porous materials are well known in nature, such as bone or wood, producing the synthetic counterparts in the laboratory is difficult. We report for the first time a straight...

— The shearing strength and volumetric relationship of granular materials change notably with a variation of confining pressure. In this study the effect confining pressure on the mechanical behavior of granular materials were observed using discrete element method (DEM). The triaxial tests were conducted on seven specimens covering a range from extremely low to high confining pressures. Each i...

The dynamic response characteristics of the innovative marine wind power hybrid foundation under combined action wind, wave and seismic loading are studied in this article. Taking monopile as reference group, shearing strain-volumetric strain coupled pore pressure incremental constitutive model was utilized to simulate kinetic behavior seabed’s saturated soil. distribution variation residual wa...

AIMS/BACKGROUND To clarify whether intraocular lens (IOL) implantation in the human eye affects the durability of polymethylmethacrylate over an average period of 10.9 years. METHODS Shearing stress and extent of damage following neodymium (Nd):YAG laser application to 18 study and 12 control optics were examined. RESULTS No significant difference was found between the study and the control...

As an abundant natural resource in Asia, bamboo is receiving increased attention as an engineering material due to its renewability and excellent strength. The parallel-to-grain compression and shearing properties of moso bamboo culm were examined. The growth characteristics (bamboo age, nodes, and location along the culm), as well as treatments for practical applications (hole punching and hoo...

In biomineralized tissues such as bone, the recurring structural motif at the supramolecular level is an anisotropic stiff inorganic component reinforcing the soft organic matrix. The high toughness and defect tolerance of natural biomineralized composites is believed to arise from these nanometer scale structural motifs. Specifically, load transfer in bone has been proposed to occur by a trans...

To improve the stretch flange deformation limit of ultrahigh-strength steels, a partial edge heating method was investigated. The effect strain gradient on when applied investigated by hole expansion test and FEM analysis. formability improved application because recovery shearing microstructure reduction hardness difference microstructure. It found that improvement for with depends region. In ...
