Numerical evaluation for debonding failure phenomenon of adhesively bonded joints at cryogenic temperatures
Source abstract
Abstract
Abstract In the present study, material characteristics, such as inelastic constitutive behaviour and debonding failure, of an adhesively bonded joint (ABJ) at cryogenic temperature have been evaluated using a computational approach. The modified Bodner–Partom model (BP model) has been introduced to describe the material nonlinearities of ABJ. The Gurson–Tvergaard model (GT model) has also been implemented into the constitutive model in order to analyse the phenomenon of debonding failure. An ABAQUS user-defined subroutine UMAT is developed using a damage-coupled constitutive model based on an implicit formulation. The numerical results are compared with a series of lap shear tests of ABJ at cryogenic temperature in order to verify the proposed method.
