How to predict failure behavior of composite high-pressure hydrogen storage tanks?

The crucial parameters or indicators for tank's failure analysis include burst pressure, damage state and fatigue lifetime, etc. So this paper gives a comprehensive review on the failure behavior analysis methods and prediction models of composite high-pressure hydrogen storage tanks from the literature.

What causes a type III composite hydrogen storage tank to fail?

The main cause of failure for Type III composite hydrogen storage tank is the fatigue failure resulting from the frequent hydrogen charging and discharging, therefore the fatigue lifetime is a crucial design indicator.

Do composite hydrogen storage tanks fail in a complex working environment?

However, the complex working environment of hydrogen-thermo-mechanism presents challenge to the failure analysis and predictive model establishment of the composite hydrogen storage tanks. The crucial parameters or indicators for tank's failure analysis include burst pressure, damage state and fatigue lifetime, etc.

Can FEA and NDT predict service life of high-pressure hydrogen storage vessels?

In this review, typical methods for optimization design, failure analysis and non-destructive testing of high-pressure hydrogen storage vessels were summarized, and the application of the FEA and NDT technologies for predicting service life and revealing damage mechanisms were discussed.

How to predict fatigue life of CFRP composite hydrogen storage tank?

Liang Wang et al. proposed a prediction method for the fatigue life of CFRP composite hydrogen storage tank. This method was based on the integration of micromechanics of failure and time-temperature superposition principle (TTSP) method under cyclic fatigue loading and high temperature conditions.

How to predict burst damage and fatigue life of Type III Composite tanks?

Various researches about burst prediction, damage identification and fatigue life of type III composite tanks were mainly based on progressive failure analysis models. These models mainly used explicit finite element method, non-interactive micromechanical failure (MMF) theory, etc.
