An analytical model for evaluating the buckling, delamination propagation, and failure behaviors of delaminated composites under uniaxial compression

Laminated carbon fibre reinforced composite materials are very susceptible to delamination, which is one of the most serious failure modes in composite laminates. According to the requests of damage tolerance evaluation, to completely evaluate the buckling responses and failure behaviors of delaminated composites under uniaxial compression, an analytical model was established. Based on the principle of minimum potential energy and brittle damage...
