“…will be satisfied through a generalized variational theory [41,42] δ g = where g is the total potential energy. Due to the arbitrariness of the variations, a system of algebraic equations can be obtained for solving the undetermined coefficients and then the deflections of the sub-beams.…”

“…For embedded delaminations, there are also a lot of solutions for delamination analysis of composite plates [41]. However, the most of the previous studies were based on FE method or other numerical solutions [42], and theoretical analysis only dealt with infinite or semi-infinite plates with cracks or finite plates having special cracks (e.g., penny-shaped crack, circle-shaped crack, edge crack, through-the-width crack).…”

Based on beam-shaped-function, the analytical solution for composite plates with arbitrary embedded delaminations is presented. The deflection function of the delaminated plate is composed by those of beams with the corresponding loading and support conditions, which can be easily and accurately derived from the beam analysis, and the deflection amplitude is derived by the minimum potential energy principle. The closed form solutions of displacements, stresses, and energy release rate of a composite plate containing an arbitrarily embedded rectangular delamination are obtained and compared with the three-dimensional finite element results to validate the accuracy of this present method. Furthermore, the influences of delamination depth, length, central position, and modulus mismatch ratio (E 1 /E 2 ) of the upper and lower sublaminate on the energy release rate are discussed.
