Composite Fatigue Simulation with VUMAT Subroutine
In this training package, VUMAT subroutine for fatigue analysis in unidirectional composites is presented. (composite fatigue VUMAT) The difference between this package and Composite Fatigue Simulation with UMAT Subroutine in ABAQUS is that acceleration effects are also included in each cycle because VUMAT subroutine works with a dynamic solver. In this training package, after the explanation of the Shokrieh fatigue theory, which is similar to mentioned package, the flowchart of the subroutine is explained. In the next step, the used subroutine is explained line by line in the undirectional composite fatigue problem.
The written subroutine on a beam is subjected to torsional fatigue loading with two different asymmetric cycles with high irregularity in two different directions. The features of this simulation are listed below.
1- Fatigue failure number (nf)
2- Residual lifetime during the iterations (Nf)
3- Residual stiffness during the iterations
4- Residual strength during the iterations
Notice: Circumstances of stiffness degradation (sudden or gradual) can be defined later.
The simulation and degradation loop of strength and stiffness in every load cycle will automatically continue until one of the stopping criteria happen. Stopping criteria in fatigue simulation can be defined as a specific number of cycles, remained lifetime or even reach to a percentage of maximum allowable stress which is suggested by us. | Unidirectional composite fatigue.
You can access all subroutine and software files immediately after purchase on your dashboard. Then, the video training will be available on your dashboard with delay. Using this tutorial package, you will learn how to model unidirectional composite fatigue with VUMAT in a dynamic problem.
