Composite Fatigue Simulation with Subroutine
Fatigue analysis in composite materials is one of the most widely used applications in today’s industry. Investigating this fatigue behavior for composite materials has many complexities and uncertainties. Scientists have tried to predict the fatigue behavior of this material at different loads by presenting various theories based on laboratory results. In this training package, by presenting the existing theories in this field and implementing them in the subroutine, it is possible to predict the fatigue behavior of composite materials and to teach you the necessary training for training as well as model upgrading.
If you are not familiar with this subroutine, you can see some information about this subroutine in ABAQUS documentation. However, you can get advanced teaching about these types of subroutines by purchasing these two packages “UMAT Subroutine (VUMAT Subroutine) introduction” and Advanced UMAT subroutine(VUMAT subroutine) in ABAQUS package.
In this workshop, the subroutine is written for a model with a shell element under cyclic loading. This subroutine will be able to display the final fatigue life, behavior of the material, including the reduction of elastic properties, strengths along with other parameters such as stress, strain, displacement, fatigue failure criteria in different modes as output. The written subroutine can be used for a variety of complex to simple models.
