Effect of Initial State and Deformation Conditions on the

This is attributed to the difficulty of deformation and the dynamic recrystallization behavior of coarse-grained samples. Moreover, fine-grained samples contain a large number of dispersed phases, which can pin the grain boundaries and inhibit the growth of recrystallized grains.

2014/7/7Using a previously developed coarse-grained model, we conducted large-scale ($ensuremath{sim}85ifmmodetimeselsetexttimesfi{}85ifmmodetimeselsetexttimesfi{}85{mat{nm}}^{3}$) molecular dynamics simulations of uniaxial-strain deformation to study the tensile behavior of an epoxy molding compound, epoxy phenol novolacs (EPN) bisphenol A (BPA). Under the uniaxial-strain


The coarse-grained soils used in the oedometer tests were sourced from the primary rock-fill of the Pankou CFRD. First, the coarse soils were roller compacted in a testing field, as shown in Fig. 1 (a) and (b); then, these coarse-grained soils were sieved into

Deformation Behavior of Coarse

This study aims to examine the deformation behavior and internal mechanism of coarse-grained soil as an embankment filler under cyclic loading. Numerical dynamic triaxial tests were performed on coarse-grained soil using the discrete element software PFC3D.

Deformation and Fracture Processes of a Lamellar

2017/4/18Coarse-grained molecular dynamics simulations can model the deformation and fracture processes of the lamellar structure in polyethylene on a molecular scale; however, the simulations have not been performed due to the difficulty in building the structure and the limitations of small-scale simulations on the order of 104 beads. Thus, we propose a crystallization method for a large-scale

Columnar grain growth in non

The growth behavior of columnar grains in non-oriented electrical steels is studied via the plastic deformation of an initial columnar-grained solidification microstructure and annealing, based on changes in grain orientation and grain orientation spread (GOS) value. The

Experimental deformation of coarse‐grained rock salt to

2016/7/29Due to these applications of rock salt, it is essential to know the deformation behavior of rock salt. Rock salt in nature is often coarse‐grained (mean grain size of most halite rocks lies between 2 and 20 mm) [Urai et al., 2008]. Inclusions filled with brine are

The influence of particle characteristics on the

Compression tests indicated that the initial load deformation response at particle–particle contact points is significantly softer than previously believed. Optical interferometry of particles after single particle–particle shearing tests confirmed that plastic strains occurred at the contact point, which were related to plastic yield.

Deformation Model of Chains and Networks with

The nonlinear stress–strain response of synthetic and biological networks and gels manifested in a monotonic increase of an instantaneous modulus is a result of the nonlinear deformation of individual network strands. To describe this behavior, we develop a nonlinear network deformation model, which relates macroscopic stress–strain response with force-elongation behavior of polymer chains

Resilient modulus and plastic deformation of soil confined

Resilient modulus tests were conducted on two coarse-grained soils (gravel and sand) and a fine-grained soil (lean silty clay) in a large-size cell with and without confinement in a geocell. The effect of the geocell on resilient modulus depended on the infill (soil in the

Deformation characteristics of coarse

2014/6/14By using large scale triaxial shearing apparatus, consolidated-drained shear tests were conducted on coarse-grained soil with different gradations. In order to describe their deformation rules, three main characteristics of tangent Poisson ratio curves were summarized and the reason was revealed by dividing the movement of soil particles into two kinds: the movement of fine particles and the
