Abstract: A remark about some unreasoning things of Oden’s constitutive variationalprinciple described in Ref. [1] is given in this paper. According to Oden’s idea, the other two constitutive variational principles, which are complementary to one another, are developed. An example is performed to demonstrate the application of the constitutive variational principles.

Key words: finite element method, postbuckling, energy release rate, delamination growth, stiffened composite laminated plate
