      A. COMPOSITE CO-CURED JOINT:1. Developed an innovative finite element modeling technique for the precise understanding of structural behavior of Bermuda Triangle region in the composite co-cured T (CCT) joint and composite co-cured L (CCL) joints. 2. This modeling technique explains the finer details of the structural behavior of the joint that other failure theories or modeling techniques failed to understand accurately to this level. 3. This modeling technique explains why and how various peaks are seen in the load Vs displacement curve obtained from the experimental procedure.B. ADHESIVE BONDED COMPOSITE (ABC) JOINTS:1. Developed an innovative finite element modeling technique for the understanding of structural behavior of adhesively bonded composite (ABC) joints. 2. Introduced a novel mechanical energy term named as "Bond Energy" which is calculated based on a particular mathematical relationship between the allowable shear strength property and Young's modulus of the adhesive materials. This energy is a new form of mechanical energy developed after a gap of nearly 250 years.3. Developed a novel failure theory based on the above Bond Energy for accurate estimation of that ultimate failure load of ABC joints tested by the third party researchers across the world. Show less
