IN THIS RESEARCH, THE MULTILAYERED COMPOSITE PLATES MADE OF GLASS/EPOXY MATERIAL WERE EXPERIMENTALLY AND NUMERICALLY INVESTIGATED UNDER COMPRESSIVE LOADING CONDITIONS. NUMERICAL FINITE ELEMENT ANALYSIS TAKING INTO ACCOUNT THE INTACT AND DEFECTED STRUCTURE. THE INFLUENCE OF THE THICKNESS AND GEOMETRICAL IMPERFECTION LEVEL WERE CARRIED OUT IN THE LINEAR BUCKLING ANALYSIS. THE NONLINEAR ANALYSIS WAS PERFORMED TO DETERMINE THE INFLUENCE OF THE DELAMINATION LENGTH ON THE BUCKLING BEHAVIOR OF THE PLATE. THE NUMERICAL RESULTS WERE VALIDATED BY EXPERIMENTS. &NBSP;EXPERIMENTAL TESTS WERE PERFORMED FOR STRUCTURES HAVING ARTIFICIAL DELAMINATION BETWEEN LAMINATE LAYERS. THE BUCKLING BEHAVIOR WAS MONITORED USING THE NONDESTRUCTIVE AND NONCONTACT STRUCTURAL VISION-BASED HEALTH MONITORING SYSTEM (THE DIGITAL IMAGE CORRELATION (DIC)). THE INFLUENCE OF THE DIFFERENT DELAMINATION BEHAVIOR DURING THE TESTS ON THE COMPRESSIVE LOAD CAPACITY WAS DETERMINED BY A DETAILED ANALYSIS OF DIC MEASUREMENTS. THE SIGNIFICANT REDUCTION OF THE COMPRESSIVE LOAD WAS NOTICED IN THE CASES WITH BUCKLING OF DELAMINATION.
