An advanced modelling approach for investigating the micromechanisms of failure of flexible composite pipes under compression

该研究计划将采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道中两种类型的微屈曲机制的不稳定性。还将研究这些管道所暴露的不同流体和环境条件的影响。所进行的研究将以实验方案为基础。了解纤维复合聚合物系统中压缩破坏的微观机制将促进纤维复合管材在现有应用中的更广泛应用，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。

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.
