Summary: Many advanced methods have been developed for predicting discrete fracture within the finite element framework, with the goal of enhancing the continuous displacement field with a discontinuous part. These methods provide unprecedented versatility in discretising domains with prescribed and evolving boundaries, but can incur additional computational burden with global tracking schemes. A new method, the Cracked Zone Clustering Method (CZCM), is proposed to address these issues by introducing minimal enhanced degrees of freedom and decoupling the discretisation of bulk and cracks. Results show that CZCM can significantly reduce the required number of enhancement degrees of freedom while maintaining accuracy.

Summary: The deformation of crack tip in PZT ceramics under cyclic electric field loading was characterized using Digital Image Correlation (DIC) technique. In-situ observation revealed the physical processes during crack propagation. The presence of incompatible deformation near the U-shaped notch was directly revealed, while no incompatible deformation was observed in the front of the newly formed crack. Crack growth occurred during the stage of crack closure. The appearance and disappearance of the incompatible domain switching zone near the U-shaped notch and around the tip of the newly formed crack were discussed based on the electrical boundary condition.

Summary: Measuring the thermal shock crack growth process is crucial for understanding the failure mechanisms and reliability of ceramic materials and structures. In this study, a self-made water quenching system was used to conduct thermal shock tests on alumina and zirconia ceramics. The thermal shock process was recorded using high-speed digital image correlation (DIC). By analyzing the speckle image change on the sample's surface, the process of thermal shock crack initiation and propagation in the two ceramics was determined. It was found that alumina exhibited a faster crack growth rate compared to zirconia, which was attributed to different material parameters. This paper presents an in-situ measurement method that can help identify and predict thermal shock damage in ceramic components.

Summary: In this study, a new strategy to prepare laminated ceramics by combining ceramic foams and hot-pressing sintering is presented. Al2O3 and ZrO2 ceramic foams prepared by the particle-stabilized foaming method were cut into thin slices and directly laminated and hot-pressing sintered. Al2O3/ZrO2 laminated ceramics with various structures were successfully prepared. The use of ceramic foams allows for easy regulation of the laminate thickness to resemble the nacre-like structure and reduces residual tensile internal stress caused by grain coarsening and differences in coefficient of thermal expansion. The optimal Al2O3/ZrO2 laminated ceramics exhibited excellent fracture toughness, flexural strength, and work of fracture.

Summary: The paper proposes an algorithm in which the values of phase field are used to identify crack paths, and physical patches are then cut by reconstructed crack paths to obtain explicit cracks and jump displacement field. The numerical examples demonstrate the predictions of various explicit cracks by the proposed method are in good agreement with literature, and Sneddon's example verifies the discontinuous displacement field across explicit cracks is consistent with the closed form solution. The proposed numerical model warrants further investigation.

Summary: The study examines the influence of different operational loading scenarios on the predicted crack growth direction for a propagating inclined railhead crack through 2D finite element simulations. It is found that a combination of thermal and contact loads results in a gradual divergence of the crack path from transverse growth to shallow growth, while a combination of bending and contact loads causes a discrete jump in the crack direction.

Summary: This study systematically investigated the tensile creep of 3 mol% Y2O3 stabilized tetragonal ZrO2 ceramics under a DC field. The results showed that the deformation mechanism of the material strongly depended on the current density and applied stress.

Summary: Phase field models for ductile fracture have been widely studied, but most existing methods only consider the effects of plastic deformation and neglect the multi-axial stress states in practical designs. In this work, a thermodynamically consistent phase field method coupled with finite strain plasticity is proposed to address this issue. The Stress-Weighted Ductile Fracture Model (SWDFM) is utilized to capture the coupling between plasticity and stress states. The excellent performance of the SWDFM in predicting ductile crack initiation motivates its incorporation into the phase field approach for predicting crack initiation and propagation.

Summary: In this work, a novel framework for modeling quasi-brittle crack propagation and shear band dominated failure of cohesive-frictional materials is proposed. The framework combines the gradient-enhanced continuum and the micropolar continuum, and is formulated based on the thermodynamically sound theory of hyperelasto-plasticity. The approach is assessed through constitutive models for particular materials and validated by numerical benchmark examples and experimental comparisons.

Summary: The coexistence of both austenite and martensite is a common characteristic in Shape Memory Alloys (SMAs). The multiple-domain microstructures, consisting of austenite, martensite twins, and individual martensite variants, evolve collectively during the phase transformation, affecting the material's macroscopic response. This paper presents an experimentally observed interface consisting of five domains in a Ni-Mn-Ga single-crystal, and analyzes the effects of thermal loading path and material initial state on the domain pattern formation.

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.

Summary: Motivated by the extraordinary strength of nacre, this study investigated the probabilistic distribution of fishnet strength using Monte Carlo simulations and found that previous analytical solutions are not applicable for fishnets with a large number of links. By approximating large-scale fishnets as a continuum with cracks or holes, the study revealed that the strength distribution follows the Weibull distribution. This new model has significance for optimizing the strength-weight ratio in printed material structures.

Summary: We have developed a simple model that describes the ionic current through neuronal membranes by considering the membrane potential and extracellular ion concentration. 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.
