Abstract
An adhesive bonding structure around a metallic mouthpiece of a cryogenic composite tank was analyzed with fracture mechanics. The energy release rate was formulated analytically by considering difference in strain energies in tension and bending before and after crack growth based on a simplified mathematical model. The analytical results were compared by finite element method calculations for five example tanks; there was a fairly good match between the analytical and numerical results. This analysis provides a guideline for the initial optimal design of a cryogenic composite tank based on fracture mechanics.
