Conic shell structures are widely used in aerospace industries. In the literature various models have been proposed to failure analysis of composite materials. Clearly, each model has a favorable range of applications. In this paper tensile, compressive, shear and thermal expansion properties of tape-wounded Carbon/Phenolic composites are firstly measured at various temperatures in range 23–200°C. The captured properties are then taken into account to progressive failure analysis of a conic Carbon/Phenolic structure under internal pressure and thermal loadings. For this end, a particular failure criterion is proposed to predict failure in the composite structures with a reasonable margin of safety. The enhanced model is then implemented into the commercial finite element software of ABAQUS via a developed user material (UMAT) subroutine utilizing a suitable solution algorithm. Advantages of the model are assessed and comparisons with other failure criteria as well as experiment are presented.

碳/酚醛胶带缠绕圆锥形壳体渐进式失效分析的特殊标准

圆锥形壳体结构广泛用于航空航天工业。在文献中,已经提出了各种模型来进行复合材料的失效分析。显然,每种型号都有良好的应用范围。在本文中,首先在23-200°C范围内的各种温度下测量绕过带子的碳/酚醛复合材料的拉伸,压缩,剪切和热膨胀特性。然后在内部压力和热负荷下,将捕获的特性考虑到锥形碳/酚结构的渐进式失效分析中。为此,提出了一种特定的破坏准则,以合理的安全裕度来预测复合结构的破坏。然后,使用适当的求解算法,通过开发的用户资料(UMAT)子例程,将增强的模型实现到ABAQUS的商业有限元软件中。评估了模型的优势,并提出了与其他失效准则以及实验的比较。
