Determination of failure envelope of functionally graded adhesive bonded joints by using mixed mode continuum damage model and response surface method
Source abstract
Abstract
Abstract In this paper, the traditional finite element analysis is combined with the statistical method in order to consider the mixed mode failure characteristics of functionally graded adhesively bonded joint. The mixed mode continuum damage model is applied considering the variation of different material parameters in the functionally graded adhesive layer and validated through some numerical examples of SLJs using ABAQUS UMAT. Taguchi method is adopted to consider the effect of different material parameters on the overall failure load of adhesively bonded joint, leading to the most influence of adhesive shear strength on the structural failure. Moreover, the response surface method (RSM) is combined with the mixed mode continuum damage model in order to determine the failure envelope of functionally graded adhesive joint and study the effect of different geometrical and material parameters numerically. The linear regression model is used to evaluate the effect of different parameters and predict the optimal condition in the design space. The current methodology enables to predict the failure behaviour including the overall failure load and the crack propagation path in the adhesive layer in the functionally graded adhesive joints with sufficient accuracy.
