Abstract

This paper provides an algorithm for the 3D printing technology, decomposing the entire surface into subdomains of different curvature, to be covered by distance holding reinforcing substructures in each subdomain. The domain decomposition is based on a draping simulation and a membrane stress analysis. The choice of printed substructures is based on our previous mathematical analysis using dimensional reduction and homogenization of textiles, stable and unstable thin fibre structures. Driving shaping mechanisms of 3D printed textiles are modelled and classified. The models are based on some previous and recent mathematical analysis work. The proposed approach is illustrated by some simulations with tool TexMath.

平面预应变驱动结构的建模，折叠到所需的表面，并应用于纺织品上的3d打印

本文提供了一种3D打印技术的算法，将整个表面分解为不同曲率的子域，在每个子域中由距离保持增强的子结构覆盖。区域分解是基于悬垂模拟和膜应力分析。印刷亚结构的选择是基于我们之前的数学分析，使用尺寸减少和均匀化的纺织品，稳定和不稳定的薄纤维结构。对3D打印纺织品的驱动成形机理进行了建模和分类。这些模型是基于以前和最近的一些数学分析工作。用TexMath工具对该方法进行了仿真。

期刊介绍： The International Journal of Engineering Science is not limited to a specific aspect of science and engineering but is instead devoted to a wide range of subfields in the engineering sciences. While it encourages a broad spectrum of contribution in the engineering sciences, its core interest lies in issues concerning material modeling and response. Articles of interdisciplinary nature are particularly welcome. The primary goal of the new editors is to maintain high quality of publications. There will be a commitment to expediting the time taken for the publication of the papers. The articles that are sent for reviews will have names of the authors deleted with a view towards enhancing the objectivity and fairness of the review process. Articles that are devoted to the purely mathematical aspects without a discussion of the physical implications of the results or the consideration of specific examples are discouraged. Articles concerning material science should not be limited merely to a description and recording of observations but should contain theoretical or quantitative discussion of the results.
