Summary: High strength aerospace alloys, such as the Al 7000 series, are prone to loss of fracture toughness during heat treatment, leading to intergranular ductile fracture. This is often caused by the formation of large precipitates at grain boundaries and the development of precipitate free zones. Consequently, grain boundaries become potential locations for micro void formation and evolution under external loads, resulting in intergranular crack formation and propagation in the material.

Summary: This study investigates the effects of grain-boundary sliding on the deformation behavior of polycrystalline aggregates using a computational framework that combines interface elements for sliding at grain boundaries and a crystal plasticity constitutive model. It is found that crystallographic orientation mismatch and anisotropic deformation play a significant role in determining the extent of grain boundary sliding. The study also quantifies the effects of grain boundary sliding on stress development within the grains and the increase in axial stress along transverse boundaries.

Summary: By coupling an improved speckle patterning method enabling high resolution digital image correlation (HRDIC) at nanoscale strain resolution with a scanning electron microscope allowing autonomous experimental control and image acquisition during in situ tensile straining, the plastic deformation in AZ31 Mg alloy at the grain scale to significant plastic strains has been mapped for the first time.

Summary: This study investigates the nanoindentation behavior of Inconel 718 polycrystalline material using a three-dimensional CPFEM simulation. The results show that the crystallographic orientation and grain boundary have little influence on the nanoindentation force-displacement curves, but significantly influence the local stress distributions and shape of the pile-up patterns. The existence of grain boundaries also affects the continuity of the stress distribution, with a larger grain boundary angle resulting in greater obstruction.

Summary: Multi-stage microforming is widely used in manufacturing complex miniaturized parts, but optimization design of the process is challenging. In this study, the influences of size effect, strain path change, and intragranularly misoriented grain boundary on deformation behaviors were investigated by conducting two-stage tensile tests on SS316L ultra-thin sheets. Increasing pre-strain and intersection angle reduced yield stress and hardening rate in subsequent tension, but the reduction became smaller with larger grain sizes. A crystal plasticity constitutive relation was established to accurately predict the mechanical response and microstructure evolution. This study provides insights for modeling and design of multi-stage microforming.

Summary: Regions with sharp local textures, known as macrozones, have a negative impact on the fatigue resistance of titanium alloys. This study developed a two-stage thermo-mechanical operation to eliminate macrozones and optimize the microstructure. The results showed that spheroidizing through dynamic recrystallization and superplasticity can achieve balling and reduce heterogeneity. The beta heat treatment followed by alpha hot compression can result in fine-grain structure and elimination of macrozones.

Summary: The coordination of grain boundary deformation is crucial for understanding the nucleation and evolution of microvoids, as well as the damage and fracture behavior of materials. However, predicting grain boundary deformation is challenging due to the complex intergranular orientation and stress state. Two important ways of coordinating deformations are the accumulation of dislocations and intergranular transfer, which are influenced by the geometric relationship of activated intergranular slip systems. Although there is a discrepancy between experimentally observed slip transfer behavior and theoretical predictions, using the crystal plasticity finite element method (CPFEM) can analyze the impact of stress state and grain orientation on grain boundary strain coordination and hardening behavior.

Summary: In this work, a physically based dislocation theory of plasticity is derived within an extended continuum mechanical context. An orientation-dependent grain boundary flow rule is introduced for the modelling of dislocation pile-up at grain boundaries and dislocation transmission through grain boundaries. The conventional grain boundary modelling approach according to Gurtin fails to satisfy the single-crystal consistency check for the limit case of adjacent grains that hold no misorientation, thus a slip system coupling based on a geometric measure of slip system compatibility is introduced. The developed grain boundary model reveals two grain boundary states, microhard and microcontrolled, for misaligned grains, enabling slip activation at grain boundaries based on the dislocation pile-up stress.

Summary: Experimental studies have revealed that many cavities are formed at grain boundaries and grain boundary triple junctions of fine-grained magnesium specimens during plastic deformation at room temperature, and the size and density of these cavities increase with the progression of deformation. The majority of cavities are controlled by plasticity, and their growth rate is similar to those observed in superplastic magnesium alloys tested at elevated temperatures.

Summary: This paper proposes a novel slip system identification framework called SSLIP, which matches the measured displacement gradient fields to the kinematics of theoretical slip systems based on crystal orientations. An optimization problem is solved for each data point to determine the amount of slip conforming to the measured kinematics, resulting in a slip activity field.

Summary: In fibrous paper materials, variations in moisture content cause changes in geometric and mechanical properties, which are strongly influenced by the inter-fibre bonds. Existing models assume perfect bonding between fibres, but in reality, even perfectly bonded fibres have some flexibility in the bond region. This study aims to assess the effect of this assumption by developing a bond model and investigating the hygro-elastic response of the paper fibre network.

Summary: The mechanical response of woven composites under off-axis tensile loading is influenced by damage in the yarn-yarn and yarn-matrix interfaces, causing yarns to rotate and reorient. Updating the material axes during loading is important to achieve realistic results, which can be done using a fiber frame stress rate description or a hyperelastic model. This study reformulates the definition of the fiber frame for woven composites and extends the implementation for an implicit solver in ABAQUS. The simulation results demonstrate a realistic stiffness evolution induced by fiber reorientations compared to the standard ABAQUS implementation.

Summary: The constitutive relation of Skorohod and Olevsky is used to model shrinkage and relative density evolution in ceramic sintering. An implicit integration scheme is presented, reducing computational cost by combining it with a solid-like shell element formulation. Material viscosity is characterized and identified using the Aquilanti-Mundim deformed Arrhenius description. The model's accuracy and efficiency are tested with benchmark experiments and the use of newly proposed material viscosity functions gives accurate predictions for dimensional shrinkage and relative density evolution, offering the possibility for more accurate and computationally efficient simulation of long-time sintering processes.

Summary: This study establishes a cytoarchitectural model to accurately capture the buckling and postbuckling behaviors of epithelia under fast compression. The stress evolution of epithelia is divided into three stages: loading, phase transition, and stress recovery. The postbuckling process is governed by the active tension generated by the actomyosin network. The study also proposes a minimal model that predicts the flattening time and stress recovery extent as functions of applied strain or strain rate, in agreement with simulations and experiments.

The model combines a simplified Poisson-Nernst-Planck model of ion transport through individual ion channels with channel activation functions calibrated from experimental data. The calibrated model accounts for the transport of calcium, sodium, potassium, and chloride and shows remarkable agreement with experimentally measured current-voltage curves for human neural cells.
