内容简介:

系统工程(System Engineering)是一个完善的过程,用于识别产品并从头到尾对其开发进行管理。解决不确定性的最佳解决方案是通过设计对噪声因素的变化不敏感并解决控制因素变化的鲁棒性设计方案,这是一种基于可靠性的解决方案,其中约束条件依概率而定,以获得控制因子中已知偏差的目标函数的概率。纤维增强复合材料不仅在力学性能上与基体材料相比具有很大的优势,而且还具备不同的功能。通过系统的研究可以准确掌握复合材料中短纤维的力学行为,从而提高复合材料的性能。应用扩展有限元XFEM方法对碳纤维增强层合复合材料在不同载荷条件下的渐进损伤进行了确定和分析,并进行了实验验证。渐进损伤理论适用于拉伸、内、横向破坏准则和破坏后行为。

Introduction:

Systems engineering is a well-developed process for identifying products and managing their development from cradle-to grave. The best solution to tackle the uncertainties is the robust design solution by making a design insensitive to the variations in noise factors and to tackle the variation in the control factors a reliability based solution in which the constraints are stated probabilistically to get the probability of an objective function for a known deviations in the control factors.

A generalized technique for determining and analyzing progressive damage in carbon fiber reinforced laminated composites subjected to various loading conditions has been developed and experimentally validated using extended finite element XFEM method. The progressive damage theory operates for tensile, inplane and transverse failure criteria and post failure behavior.
