Abstract

The paper covers the subject of FE modeling of adhesive joints, which is gaining more and more attention in the contemporary industry, especially in the aerospace and automotive sectors. This technique of creating structural connections possesses many advantages over mechanical or welding methods and it seems that it will be exploited extensively in the future mechanical design. Ability of joining dissimilar materials, decreased minimum member cross-section size and corrosion inertness can be considered as its most important features. However, in the era of virtual prototyping, it is necessary to conduct reliable computer assisted analyses of these type of joints. It is because most of the contemporary structures are developed as numerical models first, and only the final product is prototyped physically, to validate the simulation results. The aim of this paper is to demonstrate how to elaborate a reliable and accurate adhesive joint models, using a cohesive zone modeling (CZM) method. The major profitable consequence of using the CZM technique is that it introduces into the model relatively small number of spatial degrees of freedom, and therefore, allows for short computational times.
黏聚区建模方法对粘接键进行有限元分析
本文讨论了在当今工业领域,特别是在航空航天和汽车领域受到越来越多关注的粘接有限元建模问题。这种创建结构连接的技术比机械或焊接方法具有许多优点,似乎将在未来的机械设计中得到广泛利用。不同材料的连接能力、最小构件截面尺寸的减小和腐蚀惰性是其最重要的特点。然而,在虚拟样机时代,有必要对这类接头进行可靠的计算机辅助分析。这是因为大多数当代结构都是首先作为数值模型开发的,只有最终产品的物理原型才能验证模拟结果。本文的目的是演示如何利用黏聚区建模(CZM)方法来建立可靠和精确的粘接接头模型。使用CZM技术的主要有益结果是,它在模型中引入了相对较少的空间自由度,因此允许较短的计算时间。
