Summary: Pulmonary diseases driven by pollution, industrial farming, vaping, and the COVID-19 pandemic are increasing morbidity and mortality rates globally. Computational biomechanical models offer enhanced predictive capabilities to understand fundamental lung physiology. A novel reduced-order surface model of the lung has been developed in this study to address the complexities of lung structure and lack of mechanical experiments.

Summary: This study analyzed porcine lung samples using digital image correlation and an electromechanical ventilation system to understand mechanical deformations in the lung during mechanical ventilation. The results showed a linear relationship between lung volumes and local strains, and a nonlinear relationship between lung pressures and strains. Ventilation frequencies did not affect the local stretch response, strain measures increased with greater tidal volumes, and the anisotropic ratio decreased with greater inflation volumes. The study provided valuable insights for computational models and future studies on lung mechanics.

Summary: There is a growing interest in understanding the mechanical behavior of fibrous soft biological materials under different loading conditions. In this study, a fiber-reinforced soft composite was manufactured and tested to extract its mechanical behavior at different fiber orientations under mode I loading. The results showed that the J-integral obtained by DIC and the fourth-order hyperelastic strain energy function can be used to estimate the energy release rate of fiber-reinforced soft composites.

Summary: In this study, we propose a cost-effective and simple-to-implement mirror-assisted single-camera panoramic digital image correlation method for panoramic/dual-surface profile and deformation measurement. By using mirrors and an adapter, panoramic/dual-surface shape and deformation measurements can be realized in a common world coordinate system.

Summary: This article employs a Bayesian approach to estimate the micromechanical shear and bulk moduli of fiber-reinforced composite samples under the plane strain assumption and improve the handling of boundary noise. The main purpose is to quantify the effect of uncertainty in the boundary conditions in a stochastic setting. The Metropolis-Hastings Algorithm is used to estimate the probability distributions of the moduli and boundary condition parameters using IDIC, and its performance is compared to deterministic IDIC methods with introduced errors in boundary conditions.

Summary: This paper introduces a novel technique that combines full-field three-dimensional digital image correlation (3D-DIC) measurements with a topology optimization framework to detect internal or unseen damage in structural steel members. The method uses optical cameras to measure surface strains and deformations, and then employs an optimization approach to detect existing damage and reconstruct subsurface abnormalities. Experimental tests on large-scale structural steel beams demonstrate the feasibility and accuracy of the proposed method.

Summary: In this study, a method based on image processing is proposed to improve the measuring accuracy of high-temperature DIC technology. The method includes image dehazing enhancement, gray scale range stretching, and inverse filtering image recovery to eliminate the influence of thermal radiation and disturbance. Experimental results show that this method can effectively acquire high-contrast clear images under high temperature conditions and improve the measurement accuracy by eliminating the interference of thermal disturbance noise.

Summary: This paper proposes a method for nonrigidly aligning a 3D volumetric image with a 2D planar image for biological studies. By co-registering the 2D intravital microscopy videos with the more detailed 3D volume microscopy data after tissue excision, both temporal and spatial information can be combined.

Summary: This paper proposes a method for 3D reconstruction of HDR scenes through joint design and optimization of hardware and algorithms, requiring only four frames. By temporally projecting two sets of complementary speckle patterns and using a stereo matching strategy, height information encoding and pattern decoding can be achieved effectively, improving matching speed and measurable dynamic range.

Summary: A single-camera 3D-DIC system based on a fiber bundle was proposed to broaden the application range and make full use of the flexibility of the fiber bundle. The effectiveness of the method was verified through experiments, and factors affecting accuracy were analyzed along with corresponding optimization methods. The method has significant potential for determining 3D deformation in intense electromagnetic interference environment and under water due to its ability to isolate the imaging sensor from harsh environments.

Summary: An advanced in silico validation framework was established to couple the experimental and computational aspects of 3D TFM, demonstrating that the accuracy of the inverse method is improved twofold compared to the forward method. The study highlights the importance of a proper traction recovery method to minimize errors and the need for an advanced framework to assess those errors.

Summary: The study found that the tensile strength of the medial layer is the most influential factor in the initiation and propagation of aortic dissection, and the geometry and location of the tear also play important roles in the evolution of the dissection. A larger and deeper initial tear increases the risk of aortic dissection.

Summary: This paper provides a comprehensive review of computational modelling and simulations of blood vessel interaction in aortic aneurysms and dissection. Although computational models can provide clinicians with additional data, they are not widely implemented in clinical practice due to low accuracy, lengthy reporting time, and lack of numerical validation.

Summary: The endovascular technique is widely used in the first line treatment of complex aortic pathologies. The selection of a suitable stent-graft and the operator's experience play a crucial role in its clinical outcome. Numerical simulation provides a digital reproduction of endovascular interventions and can assist practitioners with decision making. This review discusses the basic principles and current literature of using numerical simulation for endovascular management of complex aortic diseases, and highlights its potential to revolutionize everyday clinical applications.

Summary: Aortic dissection is a life-threatening event with a poor outcome, involving complex phenomena that have been better understood in recent decades. However, the micro-mechanics behind the rupture events remains poorly described. Research has focused on understanding the influence of microstructure on the initiation and propagation of aortic dissection, leading to the development of multiscale models. This review aims to identify main advances and remaining questions in the field.
