Abstract
MODELING WILL BE PERFORMED FOR (I) EFFECTS OF ANISOTROPY AND NONHOMOGENEITY ON THE THREE-DIMENSIONAL STRESS FIELD NEAR SHALLOW SURFACE CUTS IN THICK LAMINATES FOR THE PREDICTION OF FIRST LIGAMENT FAILURE; AND (II) GROWTH OF DELAMINATIONS NEAR SURFACE FLAWS IN LAMINATED PLATES AND SHELLS UNDER QUASI-THREE-DIMENSIONAL STRESS STATES FOR OBTAINING FINAL FAILURE LOADS. RESULTS OF FINITE ELEMENT SOLUTIONS, APPROXIMATE FORMULATIONS AND AVAILABLE TEST DATA WILL BE COMPARED AND A COMPREHENSIVE TEST PLAN WILL BE FORMULATED. TESTS, MODEL REFINEMENTS, AND ADDITIONAL DATA CORRELATION STUDIES ARE PROPOSED IN THE FOLLOWING PHASES. THE MAIN OBJECTIVE IN PHASE I IS TO EXAMINE THE FEASIBILITY OF THE ANALYTICAL MODELING APPROACH AND ITS VALIDITY.
