Simulation of woven composite fatigue in Abaqus
The main reason for the increasing popularity of composites in weight-critical applications is their high specific stiffness and strength. Some of these advantages are better impact resistance, damage tolerance, dimensional stability over a large range of temperatures and ease of manufacturing. Some examples of engineering applications where woven composite have become indispensable are in the area of sporting goods, aircraft and aerospace, automobile and marine. In this tutorial, woven composite fatigue is presented, and you can learn how to write a subroutine for Abaqus woven composite modeling related theories.
Since, in the mentioned industries, high fatigue loads occur, it is necessary to be able to make a proper estimate regarding the fatigue life of woven composites fatigue. It should be noted that the strength and elastic properties of the structure also change by being subjected to a certain number of cycles. Therefore, the amount of stress varies after every number of cycles for constant loading. According to the mentioned explanations, it is necessary that the presented fatigue model can calculate all these cases.
In this training package, the modified Hashin fatigue damage model based on the article titled  “Life prediction of woven CFRP structure subject to static and fatigue loading “ is used. In this fatigue model, strength and elastic properties reduction and fatigue life are calculated.
In the “simulation of woven composite fatigue in Abaqus” package, all used theories, equations, and model descriptions are described at first. Then, the flowchart of the subroutine is explained. In the following, we teach you how to write subroutine line by line. It helps you to modify your subroutine based on your project theory. Finally, the written subroutine is implemented on the simple model to understand how to use this subroutine.
