Description

Simulation of cohesive fatigue in Abaqus with subroutine

Since the fatigue of cohesive is not presented as an option in the Abaqus software, it is necessary to write a subroutine to implement this behavior. In this training package, cohesive fatigue based on Khoramishad’s model has been implemented in the VUSDFLD subroutine and used on a single joint connection. Finally, the subroutine is written line-by-line and implemented on the model.FLD subroutine.

It should be mentioned the cohesive damage, as well as the damage’s progression, are both well explained. It is notable that we also considered increasing damage and applied the Benzeggagh-Kenane Fracture Criterion connection.

In this model, a reliable numerical damage model has been developed for bonded joints under a fatigue load that depends only on the adhesive system and not on the joint configuration. A bilinear tensile-separation description of a cohesive zone model was used to simulate progressive damage in bonded joints. Additionally, a strain-based fatigue damage model was integrated with the cohesive zone model to simulate the deleterious influence of fatigue loading on bonded joints. To obtain the parameters of the damage model and validate the methodology, carefully planned experimental tests on coupons cut from a bonded panel and separately fabricated single lap joints were undertaken.
