Materials containing a high proportion of grain boundaries offer significant potential for the development of radiation-resistent structural materials.However,a proper understanding of the connection
Inhomogeneous interphase is ubiquitous in heterogeneous materials,like polymer,particulate,ceramic,and cementitious composites,to name but a few.Also,inhomogeneous properties of interphase play an imp
Aiming to the difficulties of drawing the conclusion of accurate stress field and stress concentration phenomenon during the evolution of small elements discontinuous damage,an optimization algorithm
We present systematic investigations examining the shock responses of nanoporous aluminum(np-Al)by nonequilibrium molecular dynamics simulations.The dislocation nucleation sites are observed to be con
Metal additive manufacturing(AM)techniques become an important manufacturing approach for high performance complex component,which is widely used in the advanced industry.However,the defects generated
Based on the characteristic of structure on the mesoscopic level,the integrated porous micro model which considered micro voids existing in the cement mortar is established by the method of secondary
Because of the complexity of the mechanical behavior of crane girder with different damage types when it is subjected to working impact loads and the difficulty of simulating the damage process,a nove
A serials of molecular dynamics(MD)simulations for the tension/compression of polycrystalline vanadium nitride(VN)are performed to explore the effects of strain rate,tension/compression asymmetry and
The regularized variational theory of fracture,or so called phase field approach to fracture,has gained popularity due to its ability to predict crack nucleation,propagation,and branching without extr
In this study,molecular dynamics simulations were performed to study the uniaxial compression deformation of magnesium nanopillars with square and triangular surface notches.The generation and evoluti
