未固化材料的固结是厚层压复合材料结构设计和制造的一个重要因素，因为它是零件质量和缺陷形成的关键驱动因素。这里介绍了一种新的建模方法及其实现。基于运动学富集的本构关系是从材料微观成分的取向和体积、它们各自的本构定律以及它们之间的界面的取向推导出来的。它适用于任何层状结构，特别是由软各向异性材料制成的层状结构。所提出的方法已通过用户材料实施到商业有限元（FE）软件中。它在层压复合材料制造过程中预测皱纹的能力证明了其作为设计工具的性能，因为这为任何数值平台提供了具有挑战性的测试用例。 (C) 2019 年由爱思唯尔有限公司出版。
The consolidation of uncured material is an important factor in the design and manufacture of thick laminated composite structures since it is a key driver for part quality and the formation of defects. A new modelling approach and its implementation is presented here. The constitutive relation, based on kinematic enrichment, has been derived from the orientation and volume of the micro-constituents of the material, their respective constitutive laws and the orientation of the interfaces between them. It is applicable for any layered structures, in particular those made of soft anisotropic materials. The proposed method has been implemented into a commercial Finite Element (FE) software via a user material. Its ability to predict wrinkles during the manufacture of laminated composites demonstrates its performance as a design tool, as this provides a challenging test case for any numerical platform.
