The research programme will employ both semi-analytical models and advanced numerical techniques to develop predictive tools for the onset of instabilities responsible for the two types of observed microbuckling mechanisms in flexible composite pipes. Effect of different fluids and environmental conditions to which these pipes are exposed will also be investigated. The research carried out will be built on the experimental programme. Understanding of the micro-mechanisms of compressive failure in fibre composite polymer systems will promote more widespread use of fibre composite pipe in existing applications and provide options for harsher environments. This will allow more effective exploitation of hydrocarbon reserves.

该研究方案将使用半分析模型和先进的数值技术来开发预测工具，以预测导致柔性复合管中观察到的两种微屈曲机制的不稳定性的开始。此外，我们亦会调查不同流体和环境条件对这些管道的影响。开展的研究将建立在实验方案的基础上。了解纤维复合材料聚合物系统中压缩破坏的微观机制将促进纤维复合材料管道在现有应用中的更广泛使用，并为更恶劣的环境提供选择。这将允许更有效地开采碳氢化合物储量。
