Abstract This work outlines an efficient deep learning approach for analyzing vascular wall fractures using experimental data with openly accessible source codes ( https://doi.org/10.25835/weuhha72 ) reproduction. Vascular disease remains the primary cause of death globally to this day. Tissue damage in these disorders is closely tied how diseases develop, which requires careful study. Therefore, scientific community has dedicated significant efforts capture properties vessel fractures. The symmetry-constrained compact tension (symconCT) test combined digital image correlation (DIC) enabled study tissue fracture various aorta specimens under different conditions. Main purpose experiments was investigate displacement and strain field ahead crack tip. These were support development verification computational models. FEM model used DIC information material parameters identification. Traditionally, analysis processes biological tissues involves extensive due complex nature behavior stress. high costs have posed challenges, demanding solutions accelerate research progress reduce embedded costs. Deep techniques shown promise overcoming challenges by indicate patterns relationships between input label data. In study, we integrate methodologies attention residual U-Net architecture predict responses porcine specimens, enhanced a Monte Carlo dropout technique. By training network on sufficient amount data, learns features influencing progression. parameterized datasets consist pictures describing evolution path along measurements. integration should not only enhance predictive accuracy, but also significantly burden, thereby enabling more response.

Abstract Data scarcity is a major challenge when training deep learning (DL) models. DL demands large amount of data to achieve exceptional performance. Unfortunately, many applications have small or inadequate train frameworks. Usually, manual labeling needed provide labeled data, which typically involves human annotators with vast background knowledge. This annotation process costly, time-consuming, and error-prone. every framework fed by significant automatically learn representations. Ultimately, larger would generate better model its performance also application dependent. issue the main barrier for dismissing use DL.

Abstract Advancements in computing power have recently made it possible to utilize machine learning and deep push scientific forward a range of disciplines, such as fluid mechanics, solid materials science, etc. The incorporation neural networks is particularly crucial this hybridization process. Due their intrinsic architecture, conventional cannot be successfully trained scoped when data are sparse, which the case many engineering domains. Nonetheless, provide foundation respect physics-driven or knowledge-based constraints during training. Generally speaking, there three distinct network frameworks enforce underlying physics: (i) physics-guided (PgNNs), (ii) physics-informed (PiNNs), (iii) physics-encoded (PeNNs). These methods advantages for accelerating numerical modeling complex multiscale multiphysics phenomena. In addition, recent developments operators (NOs) add another dimension these new simulation paradigms, especially real-time prediction systems required. All models also come with own unique drawbacks limitations that call further fundamental research. This study aims present review four (i.e., PgNNs, PiNNs, PeNNs, NOs) used state-of-the-art architectures applications reviewed, discussed, future research opportunities presented terms improving algorithms, considering causalities, expanding applications, coupling solvers.

Abstract The rapid growth of deep learning research, including within the field computational mechanics, has resulted in an extensive and diverse body literature. To help researchers identify key concepts promising methodologies this field, we provide overview deterministic mechanics. Five main categories are identified explored: simulation substitution, enhancement, discretizations as neural networks, generative approaches, reinforcement learning. This review focuses on methods rather than applications for thereby enabling to explore more effectively. As such, is not necessarily aimed at with knowledge learning—instead, primary audience verge entering or those attempting gain discussed are, therefore, explained simple possible.

In this work, we proposed a robust radial point interpolation method empowered with neural network solvers (RPIM-NNS) for solving highly nonlinear solid mechanics problems. It is enabled by via minimizing an energy-based functional loss. The RPIM-NNS has the following key ingredients: (1) uses basis functions (RBFs) displacement at arbitrary points in problem domain, permitting irregular node distributions. (2) Nodes are placed also beyond domain boundary, allowing convenient implementation of boundary conditions both Dirichlet and Neumann types. (3) strain energy integral form as part loss function, ensuring solution stability. (4) A well-developed gradient descendant algorithm machine learning employed to find optimal solution, enabling robustness ease handling material geometrical nonlinearities. (5) compatible parallel computing schemes. performance tested using problems including Cook's membrane 3D twisting rubber problems, demonstrating its remarkable stability robustness. This which seamlessly integrates governing equations computational techniques, offers excellent alternative MATLAB codes made available https://github.com/JinshuaiBai/RPIM_NNS free downloading.
