As known, the weight of structures is one of the principle concerns in transport engineering. In this relation, the multilayered structural materials with their high strength-to-weight and stiffness-to-weight ratios are excellent for application in transport engineering. However, delamination is one of the momentous disadvantages of multilayered structural members. Therefore, a multilayered delaminated beam structure exhibiting linear relaxation behavior is studied in this paper. The beam under consideration is statically undetermined. The angle of rotation of the cross-section located near the beam left-hand end is fixed in order to generate conditions for relaxation of stresses. There is a delamination crack in the beam. The time-dependent problem of the energy release rate (ERR) for the delamination crack is solved. For this purpose, an analysis that takes into account the relaxation of stresses is developed by considering the compliance of the beam. An alternative approach is used for verification. The effect of the beam static indeterminacy on the ERR is assessed.
