Then, based on the experimental observations, a fractional viscoelastic-viscoplastic constitutive model is constructed from the proposed Gibbs free energy and viscoplastic dissipation potential. The viscoelastic part is described by the fractional Poynting-Thomson model, and the viscoplastic one is reflected by the improved Armstrong-Frederick kinematic hardening rule under the unified viscoplastic model with the fractional derivative. Additionally, the mapping relationships between the crosslink density and the viscoelastic and viscoplastic model parameters are also, respectively, introduced into the proposed model. Furthermore, an implicit stress integration algorithm for the proposed model and a method to determine the model parameters are proposed.

The shapes of non-planar shock wave in nanocrystalline dual-phase titanium alloys were affected by the distribution of second phase grain.

Analytical solutions are found under some specific loading paths, which make it possible to perform relevant critical analyses on mechanical behaviors of quasi-brittle solid. It is interestingly found that cracks in critical families propagate predominantly, especially in the post-peak phase, by controlling material failure and leading to the localization from diffuse damage (microcracks) to one or several macro cracks.

In this work, the same AM parameters resulted in obvious difference in elemental segregation and grain heterogeneity between AM CoCrNi MEA and CoCrFeMnNi HEA, which generated unusual temperature-dependent strain hardening and ductility: First, although the strength and strain hardening of MEA were always higher than those of HEA, the gaps gradually decreased when the temperature decreased from 293 K to 5 K. It was related to solidification parameters, i.e., higher cooling rate and shallower melt depths in MEA, leading to more fine grains. Higher grain heterogeneity in MEA suppressed its deformation twinning (DT) behavior and thereby degrades the hardening capacity at cryogenic temperatures. Secondly, two materials showed an opposite tendency in the temperature-dependent ductility. MEA presented ductility loss at the cryogenic temperature range while HEA displayed an increased ductility. When temperature is 5 K, the ductility of HEA even surpassed MEA. Fracture behavior and molecular dynamics imply that the Cr segregation in MEA reduces the grain boundaries (GBs) cohesive strength, together local stress concentration at the GBs induced by high-density DTs, resulting in the presence of intergranular cracks at cryogenic temperatures.

A traction-separation relationship that can be experimentally calibrated is incorporated into the cohesive law of the proposed model, and the degradation of the fracture toughness caused by the localized accumulation of plastic deformation (captured by the crystal plasticity theory) is quantified through a degradation function. The simulation results demonstrate that the relatively high localized accumulated plasticity (leading to a damage accumulation) and elastic energy (providing the main driving force) can lead to microcrack initiation and propagation in NiTi SMAs during cyclic loading. When both the accumulated plasticity and elastic energy are relatively high in a local region, the propagation rate of microcracks in such a region is significantly higher than that of the microcracks in other regions or with only one dominant factor (e.g., accumulated plasticity or elastic energy). The different microstructural evolutions of austenitic and martensitic NiTi SMAs induce distinct distributions and magnitudes of elastic energy and accumulated plasticity, which drive their different microcrack evolutions. The synergistic influence of elastic energy and accumulated plasticity on microcrack evolution is effectively described by the proposed model.

During plastic deformation, dislocations interact with GBs in various ways—they may transfer to adjacent grains, reflect back, or be absorbed—depending on the GB's properties. Past attempts to understand these effects have predominantly relied on atomistic simulation with limited spatiotemporal scales. Here, we exploit an \"all-dislocation\" density (ADD) dynamics framework to simulate plasticity within grains and at GBs. We derived a flux boundary condition for ADD that incorporates the dislocation density flux at the GB and implements it numerically on a rhombus mesh structure. The dislocation flux is computed using a mathematically robust framework that rigorously accounts for factors affecting slip transfer. The numerical scheme examines the effects of misorientation angle and grain size on slip transfer under constant stress, constant stress rate, and constant strain rate conditions. The results reveal that lower misorientation angles lead to higher plastic strain and mobile dislocation density. Furthermore, plastic strain is inversely proportional to the square root of the grain size, aligning with the Hall–Petch relationship. Strain hardening intensifies with increasing grain boundary misorientation, reflecting reduced slip transfer through less permeable boundaries. The study also investigates how mobility and initial dislocation density influence lattice resistance and GB strengthening, revealing transitions between hardening mechanisms. These expected results confirm that the ADD framework is appropriate for mesoscopic simulation of GB effects in dislocation plasticity.</div></div>","PeriodicalId":340,"journal":{"name":"International Journal of Plasticity","volume":"196 ","pages":"Article 104554"},"PeriodicalIF":12.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145559714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, a modified isotach viscosity formulation is first extended to account for hydrate conditions, with the creep coefficient expressed as an exponential function of hydrate saturation. Secondly, a two-surface (loading and yield surfaces) framework is formulated, integrating multifactorial viscoplastic hardening mechanisms, namely isotropic hardening, progressive hardening, and deviatoric degradation, along with a Caputo-formed non-orthogonal viscoplastic flow rule. Then, employing the consistency condition of the loading surface, an incremental constitutive relation is rigorously formulated to explicitly relate stress, strain, strain rate, temperature, pore pressure, and hydrate saturation. Finally, validation against experimental data demonstrates the model’s excellent capability to simulate mechanical behaviors under complex time-dependent stress paths.

This investigation examines the influence of crystallographic orientation relationships and stress states on fundamental characteristics of slip transfer behavior at phase boundaries and grain boundaries.
