DELAMINATION OF MULTILAYERED BEAMS WITH NON-LINEAR VISCOELASTIC BEHAVIOUR UNDER STRAINS OF STEP-LIKE VARYING VELOCITY

V. Rizov, H. Altenbach

The present paper deals with delamination analysis of a multilayered inhomogeneous beam structure that exhibits non-linear viscoelastic behaviour under strains whose velocity varies step-like with time. There are two delaminations in the beam. The left-hand delamination crack arm is subjected to bending so as the velocity of angle of rotation of this crack arm varies step-like with time. A non-linear viscoelastic model with a spring and two dashpots treats the beam mechanical behaviour. Solutions of the strain energy release rate are derived for both delaminations. A parametric investigation of delamination in the beam is carried-out by using the solutions.
