| dc.description.abstract | Adhesively joining technique becomes very important due to capability like joining dissimilar material, lighter vehicle design, and composite material assembly than mechanical fastening. During combining dissimilar or similar materials together there must be adequate understanding of the behavior of multi-material adhesively bonded joints to ensure efficiency, safety and reliability of such joints. This may include adhesive thickness, bond length, amount of load to be applied, type material to be joined, type adhesive to be used and other factors used in analysis parameters. Using Elastomeric adhesives such as polyurethanes Sikaflex 265 as adhesive and steel, aluminum, glass and composite as adherend, analytical and numerical analysis has been done on single lap joint for elastic limit. In analytical, derivation of analytical equation that describe peel and shear stress profiles along adhesive length which is to be validated by comparing to numerical analysis done by Finite Element commercial package ABAQUS for metals. By varying the parameters used in stress equation derivation the effect they have on strength of joint also shown on failure load determination for steel, glass and aluminum. For all metals the analysis done is valid for elastic Range only. Effect of fiber orientation of glass fiber reinforced polymer (GFRP) composite on the joint also analyzed. Selecting suitable failure criteria then failure load for each combination of joint parameters are done. | en_US |
