Abstract

MECH-Gcomp was developed as web-based free software to aid in learning and to help researchers and industry professionals in failure analysis of composite materials. The software is already well-established for the study of micromechanics and has extended to other fields. This work focuses on one of its newest modules, related to the failure analysis of composite laminae, for which thirteen different failure criteria were implemented, along with an important tool for the construction of failure envelopes. The programming and characteristics of this module are presented and discussed. In addition, jute/polyester composites were manufactured and tested under different stress states to verify the software predictions. The root-mean-square error ranged from 0.096 to a maximum of 0.545, and most of the analyzed criteria yielded reasonable agreement compared to the experimental data. A significant variation in predictions among the criteria could be clearly observed, especially based on the produced failure envelopes for the different stress states.

开发基于网络的复合材料层压板失效分析软件

MECH-Gcomp 是一款基于网络的免费软件，旨在帮助研究人员和工业专业人员学习和分析复合材料的失效。该软件已在微观力学研究中得到广泛应用，并已扩展到其他领域。这项工作的重点是其最新模块之一，与复合材料层的失效分析有关，其中实施了 13 种不同的失效标准，以及构建失效包络的重要工具。对该模块的编程和特点进行了介绍和讨论。此外，还制造了黄铜/聚酯复合材料，并在不同的应力状态下进行了测试，以验证软件的预测结果。均方根误差从 0.096 到最大 0.545 不等，与实验数据相比，大多数分析标准都取得了合理的一致。根据不同应力状态下产生的失效包络线，可以清楚地观察到不同标准的预测结果存在明显差异。
