Abstract EN
This paper presents the determination of the interlaminar stresses close to the free edges of general cross-ply composite laminates based on higher order equivalent single-layer theory (HESL).
The laminates with finite dimensions were subjected to a bending moment, an axial force, and/or a torque for investigation.
Full three-dimensional stresses in the interior and the boundary-layer regions were determined.
The computed results were compared with those obtained from Reddy’s layerwise theory.
It was found that HESL theory predicts precisely the interlaminar stresses near the free edges of laminates.
Besides, high efficiency in terms of computational time is obtainable when HESL theory is used as compared with layerwise theory.
Finally, various numerical results were presented for the cross-ply laminates.
Also design guidelines were proposed to minimize the edge-effect problems in composite laminates.
