Buckling analysis of tri-layer beams with multiple separated delaminations
Buckling analysis of tri-layer beams with multiple separated delaminations
In the present work, nondimensionalized axial and bending stiffnesses are used to investigate the buckling behavior of tri-layer beams having asymmetric double separated delaminations. A generalized analytical analysis using the Euler–Bernoulli beam theory is developed. Appropriate boundary and kinematic conditions are used to formulate the systematic homogeneous equations. The model is verified with the previously published data for homogeneous beam case and an excellent agreement between the results is observed. Effective-slenderness ratio, a new nondimensionalized parameter, is defined and introduced which strongly influences the buckling phenomenon.

Abstract
In the present work, nondimensionalized axial and bending stiffnesses are used to investigate the buckling behavior of tri-layer beams having asymmetric double separated delaminations. A generalized analytical analysis using the Euler–Bernoulli beam theory is developed. Appropriate boundary and kinematic conditions are used to formulate the systematic homogeneous equations. The model is verified with the previously published data for homogeneous beam case and an excellent agreement between the results is observed. Effective-slenderness ratio, a new nondimensionalized parameter, is defined and introduced which strongly influences the buckling phenomenon.
