Failure Analysis of Structural Adhesive Joints with Functionally Graded Tubular Adherends
The present research has focused on exploring the use of functionally graded adherends in place of laminated FRP composite tubular adherends in a bonded Tubular Single Lap Joint (TSLJ) subjected to uniaxial tensile loading with the sole objective of reducing stress concentration in the joint region. Elastic properties (E, υ) of tubular adherends of a structural adhesive joint have been varied as per the Power‐law function based gradation. Suitable ANSYS Parametric Design Language (APDL) codes have been developed for modeling and analysis of a functionally graded structural adhesive joint and have also been validated with results from analytical models proposed in literature. The developed APDL codes are capable of suitably grading the material properties (E, υ) along axial direction of tubular adherends. Structural SOLID 185 elements of ANSYS 18.0 have been used for discretizing the structural adhesive joint region. Effect of variation of layer number (M) has been studied for an optimum number of axial divisions for smooth variation of properties without compromising the minimum possible CPU time and computational accuracy. Finally, stress and failure analyses of the adhesive joint region have been carried out for optimum layer number and a specific value of the compositional gradient exponent (n = 0.1).
