Composite pressure vessel in ABAQUS
This training package professionally provides tips for designing and simulating type 3 and 4 composite pressure vessels. It should be noted that the WCM plug-in is widely used to simulate these vessels. In this package, various winding methods of simulation methods of composite pressure vessels are presented. As you know, composite pressure vessel design has variations in angle and thickness in the dome area depending on the type of winding method. This training package teaches scripting for the automatic simulation of composite pressure vessels with three methods of geodetic, isotensoid, and planar winding. UMAT subroutine is also examined to identify the failure initiation and continuation of the failure based on a PUCK criterion. It is better to say that, here in this package, Abaqus composite pressure vessel design considerations are fully discussed.
Filament-wound composite pressure vessels, which utilize a fabrication technique of filament winding to form high-strength and lightweight reinforced plastic parts, are a major type of high-pressure vessel and are widely used in the commercial and aerospace industries such as fuel tanks, portable oxygen storage, rocket motor cases and so on. This kind of vessel consists of a cylindrical drum and dome parts, just like typical pressure vessels. The trajectory of the fiber path and the corresponding
fiber angles cannot be chosen arbitrarily because of the stability requirement.
It would be useful to see Abaqus Documentation to understand how it would be hard to start an Abaqus simulation without any Abaqus tutorial. If you are working on Abaqus composite damage and need some resources about composite FEM simulation, click on the Abaqus composite analysis page to get more than 20 hours of video training packages on composite materials simulation. If you have no initial information about composite pressure vessel design, it would be useful to check our basic articles in the blog section.
You can access the subroutines, Matlab, Abaqus, and subroutines files after purchase immediately.Video files will be available about 2 months after purchase.
In comparison to metals, composites’ damage mechanisms are less well known. Composite materials and structures are susceptible to defects, whether they appear during material processing, component fabrication, or in-service use. Understanding how the damage or defect affects the structural integrity of the composite component is crucial to determining how critical the defect is. If we can somehow determine these damages and tend to them in time, the maintenance cost would be severely decreased. Also, our design will be better and well-optimized.
It’s true that the composite structures have sufficient strength and stiffness but like other structures, they may get damaged during the service. The damages could be caused by impact, low resistance to the service environment, overloading, Staff carelessness, etc.
In-service damages include:
- Impact damage
- Fiber fracturing
Service flaws in composite structures are typically caused by impact damages. Delamination is the most frequent impact-related damage. Delamination occurs when layers in a laminated composite are split, creating a mica-like structure with a considerable loss in mechanical properties. Delamination is the separation of the laminate at the boundary between two layers as a result of shock, impact, or repeated cyclic pressures. Individual fibers can pull away from the matrix, for instance.
It is the engineer’s duty to analyze the structures and determine the defects and damages so that the structure can keep working properly and lower the cost of maintenance. With the help of Computer-aided engineering (CAE) and finite element method (FEM), you would be able to do this task in the best way possible.
We are here at the CAE Assistant to explain some about composite material damage and introduce some FEM tools to simulate these damages correctly. Also, we will help you out learn how to simulate and analyze your model and structure. With our high-quality education, you can learn how to work with the Abaqus and analyze composite structures. I recommend you read the topics of this training package on the right side of this page and if you have more questions about this package and its content and quality, ask on the live chat on the left side of this page.

I can say that this package is one of the most complete training packages about composite vessel analysis. With the help of this package, I was able to solve all my problems and questions about composite vessel. I will definitely recommend this package to others.
Thank you for preparing this tutorial. It was perfect. Do you have another tutorial on progressive damage on vessel?
According to the description, this package almost covers any necessary information. Don’t you have any free version of this package?
