  A numerical study has been carried out on stiffened composite panels under compression, focusing on the delamination-related phenomena. A robust numerical finite elements model has been introduced to simulate the compression behavior of the panel, including the delamination buckling and growth, and to provide reasonable predictions of the strain Cited by: the material constituent on the damage mechanism is computed. We also give an assessment of the strain energy release rates associated with each damage mode. This criterion checked on glass-epoxy and graphite-epoxy composite materials will now be used in future research on new bio-based composite in the laboratory. Some results of numerical simulations of the post-buckling delamination growth in compressed composite plates and shells are presented in [14,15,16,17].A finite-element nonlinear analysis of the post-buckling behavior of a compressed rectangular plate with circular delamination was conducted in [] with the ABAQUS code and validated by experimental : Alexander A.

Introduction Composite materials are very often used, but strength with large deformation is still problem [11]. A key factor in the design of structures from composite materials is the prediction of failure of the fibre, matrix and interlaminar delamination. The employment of composite materials in the aerospace industry has been gradually considered due to the fundamental lightweight and strength characteristics that this type of materials has.
