45567 2018 eng lecture 0 -- -- -- BAM has discovered that the reliability of tested composite pressure vessel will be altered when the loading speed is varied. The ageing of composite materials in general gives negative effect to the structure, however there might be positive effect occurs due to the load redistribution between the fibres. The study on the negative effect of ageing has been compared favourably with the fibre break model from Mines ParisTech. To improve the model's capability, this positive effect should also be implemented. The problem however to evaluate real scale model that might take extensive computation time. The reduced volume method then was proposed to improve the calculation time. The next study is then to check the approach on different loading condition and compare the result with experimental data provided by BAM.
