abstract = {In this article, we present a multi-scale plastic-damage model for strain-induced morphological anisotropy in semi-crystalline polyethylene formulated within a continuum-based micromechanical framework. The crystallographic shear in the crystalline lamellae and the molecular alignment/relaxation of the amorphous phase are two underlying inelastic processes integrated in the constitutive representation. The cavitation damage accumulation related to the progressive nucleation and anisotropic growth of nano-sized cavities in the amorphous phase is also integrated and treated separately for the elastic–viscoplastic intermolecular interactions and for the viscohyperelastic network interactions. The mechanical coupling between the deformation modes in the amorphous and crystalline domains is obtained by considering the crystalline–amorphous interfacial interaction in the micro-macro homogenization procedure. We compare the model output to tensile experimental observations from the literature of high-density polyethylene, in terms of stress–strain response and inelastic volumetric strain, during stretching and stretching-retraction-recovery sequences upon large-strain plastic deformation at different strain rates and temperatures. We analyze the effect of strain-induced morphological anisotropy on the internal cavitation damage distributions by means of pole figures. The key role of the cavitation damage on the macroscopic and internal responses is studied.},

abstract = {The present work is devoted to a deep analysis of the hydrated surface properties of Calcium-Silicate-Hydrate (CSH) by means of molecular dynamics simulations and reactive force fields (REAXFF). The radial distribution function shows that the relative coordinates among atoms inside films structure is the same as the bulk one. Moreover, the (001) surface free energy of CSH is found in the range of 698 erg/cm2to 740 erg/cm2. The smallest and biggest averaged contact angle between equilibrated water nanodroplet and CSH surface is 23.62° and 29.29°, respectively, which reveals the hydrophilic behavior of the (001) surface. The work of adhesion between water-nanodroplet and CSH surface is 136.47 × 10−3 J/m2. The spreading area of nanodroplet onto CSH surface is a defect circle and the distance between most of relaxed water molecules and CSH surface is within 3.2 Å.},

abstract = {The current work investigates the effects of branching and temperature on the mechanical properties and shape memory properties of branched polyethylene. The results show that the mechanical properties of low density polyethylene are strongly influenced by the length, number and temperature of the branched chains. The lower the temperature, the lower the modulus of elasticity. When the length is longer and the number is smaller, the stress in the hardening phase is higher. For shape memory properties, we found that the fewer and shorter the branched chains, the better the shape memory properties, and the shape memory behavior can promote the repolymerization and crystallization of the structure, which will cause the enhancement of stress hardening.},

abstract = {The mechanical behavior of montmorillonite is sensitive to water content and structural anisotropy. In this study, the evolution of atomic structure and mechanical behavior of different hydrated montmorillonite under tension has been investigated using Molecular Dynamics simulations. External deformation has been applied to montmorillonite with a strain rate of 5 × 10−7 fs−1 for uniaxial tensile test, stretched along directions parallel (x- and y-direction) and perpendicular (z-direction) to the clay sheets. The bond-breakage criterion based on the radial distribution function of atom pairs and the evolution of broken bonds with tensile strain, were applied to explore the deformation and failure mechanism of the montmorillonite-water system. Simulation results indicated that the water content increased, causing a decrease in the ultimate tensile strength and Young's modulus, as well as more and more plasticity for montmorillonite, especially in z-direction. Moreover, the sequence of tensile mechanical strength was y > x > z. Stretching along the x- and y-direction, fractures occurred in the silicon‑oxygen tetrahedral and aluminum‑oxygen octahedral sheets, where the aluminum‑oxygen bond was easier to be broken, and the normalized number of total broken bonds in the y-direction was superior to the x-direction. Stretching along the z-direction, only the hydrogen bonds in the interlaminar space were broken. In terms of three directions, the anisotropy behavior was found in ultimate tensile strength, Young's modulus, residual tensile strength, and the evolution of broken bonds.},

abstract = {The mechanical behavior of ice is complex, especially with the effect of temperature and pressure, which may significantly affect the safety in various engineering, where slow deformation of ice may bring more hidden, sudden, and severe damage. The mechanical behavior of ice-Ih under a low strain rate with the effect of temperature and confining pressure is still unclear, especially at the nanoscale. In this work, the tensile behavior of ice-Ih is investigated using Molecular Dynamics simulation method. The tensile test of ice-Ih was all performed along the y-direction ([010] crystal orientation) with a constant strain rate of 1 × 108 s−1. The effect of temperature (73 to 270 K with 1 atm), as well as the confining pressure (1 atm to 200 MPa, combined with 100 K, 150 K, 200 K, and 250 K) on the tensile behavior of ice-Ih, was studied, respectively. The tensile stress–strain response under different temperatures was obtained, and the linear relationship of temperature and Young’s modulus was consistent with other previous studies. The tensile strength of ice-Ih decreased linearly with increasing temperature under low strain rate, which is quite different from the cases under high strain rate. The solid-solid phase transition was observed at 73 ∼ 140 K, and the solid-liquid phase transition at 150 ∼ 270 K, where more energy is required in completely solid-liquid phase transition at 250 ∼ 270 K than solid-solid phase transition at 73 ∼ 140 K. The evolution of total potential energy increment and structural failure with strain significantly depended on the phase transition of ice-Ih. Moreover, the ice-Ih is earlier and more likely to be melted at higher confining pressure.},

abstract = {The platinum-group elements (PGMs) owing their high chemical stability, and unique properties, have recently attracted great research interest in various promising applications. Herein using state-of-the-art first-principles evolutionary algorithms, we explore the thermodynamic and mechanical properties of Ir, Os, and their alloys. Hitherto unknown polytype-phases of Ir (6H, 4H, 2H) and Os (6H, 4H) have been predicted, two of these (4H-Ir, and 4H-Os) were recently observed experimentally. Os and, to more extent, Ir polytypes divulge weak thermodynamic instabilities. Phonon dispersion and elastic constants calculations were carried out to demonstrate the dynamical and mechanical stabilities of these phases. For the Ir-Os alloys, four ordered structures (Pm-3 m (IrOs3, Ir3Os), P-6 m2 (IrOs), P-3 m1 (IrOs2)) have been predicted, which are found mechanically and dynamically stables and manifest insignificantly thermodynamic instabilities. Furthermore, our obtained results show that Ir-Os systems evince outstanding mechanical properties, IrOs3 has high bulk modulus (∼421GPa), large shear modulus (∼266GPa), and Young’s modulus (659 GPa); whereas IrOs2 possesses a remarkable large elastic constants C11 (779GPa) and C33 (814GPa). The anisotropic calculations show that IrOs3 exhibits that greatest anisotropy in the universal elastic anisotropy index AU, shear modulus (AG) and Young’s modulus (AE); while IrOs2 has the smallest elastic anisotropy. Moreover, IrOs3 reveals distinguished hardness of 27.6GPa, which is 3% weaker than 2H-Os (28.6GPa), and is so far one of the hardest materials among the PGMs binary alloys.},
