摘要

在本研究中，揭示了螺栓叠合复合材料结构力学分析的基本步骤。利用MARC/MENTAT有限元软件，在Fortran和Python语言中开发了实现复合材料模型非线性化的先进方法。HTA/6376 CFRP材料的摩擦和损伤参数使用文献中的实验数据源进行验证。计算了具有各向异性特性的aisi304l薄板材料的临界Cockroft-Latham韧性损伤参数，以满足复合接头中塑性变形金属构件的设计要求。CFRP复合材料的摩擦和渐进损伤、AISI 304L的延性损伤与外部实验文献吻合较好。

Fastening solutions on composite structures: model and verifications of contact with friction, progressive composite damage, and ductile metal damage

In this study, the fundamental steps required for the mechanical analysis of bolted laminated composite structures were revealed. Advanced methods were developed in Fortran and Python to implement nonlinearity to the composite material model using MARC/MENTAT finite element software. Friction and damage parameters for HTA/6376 CFRP material are verified using experimental data sources in the literature. The critical Cockroft–Latham ductile damage parameter of AISI 304L sheet material with its anisotropic properties, which is required for the design of plastically deformable metal components in the composite joint, is computed. Good agreement was obtained between the friction and progressive damage of CFRP composite, ductile damage of AISI 304L, and the external experimental references.

期刊介绍： Serving the multidisciplinary materials community, the journal aims to publish new research work that advances the understanding and prediction of material behaviour at scales from atomistic to macroscopic through modelling and simulation. Subject coverage: Modelling and/or simulation across materials science that emphasizes fundamental materials issues advancing the understanding and prediction of material behaviour. Interdisciplinary research that tackles challenging and complex materials problems where the governing phenomena may span different scales of materials behaviour, with an emphasis on the development of quantitative approaches to explain and predict experimental observations. Material processing that advances the fundamental materials science and engineering underpinning the connection between processing and properties. Covering all classes of materials, and mechanical, microstructural, electronic, chemical, biological, and optical properties.
