Wherever you are, if you are working on the pipe bending process, the Bending Pipe Plugin allows you to speed up the modeling process, and easily analyze and improve it with parametric facilities.
Pipe bending is a process of deforming a pipe into a specific shape or angle using specialized equipment and techniques. It is commonly used in industries such as construction, plumbing, and manufacturing. There are several different types of pipe bending processes, including:
- Mandrel bending: This process involves inserting a mandrel (a solid rod) inside the pipe while it is being bent. The mandrel helps maintain the shape and prevents the pipe from collapsing or wrinkling during the bending process.
- Rotary draw bending: In this method, the pipe is clamped at both ends and rotated while a die (a curved tool) is used to bend it. This process allows for precise and accurate bending.
- Roll bending: In roll bending, the pipe is passed between three rolls – two bottom rolls and one top roll. The top roll applies pressure to bend the pipe as it passes through the bottom rolls. This process is commonly used for large-diameter pipes.
- Heat induction bending: This process involves heating the pipe to a specific temperature using induction coils. Once heated, the pipe is bent using hydraulic or mechanical force. Heat induction bending is often used for pipes made of materials that are difficult to bend, such as stainless steel.
- Ram bending: Also known as press bending, this method involves using a hydraulic ram to press the pipe against a die to achieve the desired bend. Ram bending is commonly used for large pipes or when a small number of bends are required.
The materials that can be used for pipe bending depend on the type of bending process and the desired outcome. Some of the commonly used materials for pipe bending include stainless steel, aluminum, copper, brass, carbon steel, and titanium. The selection of the material also depends on the application and the environment in which it will be used. For example, stainless steel is often used in applications where corrosion resistance is required, while aluminum is preferred for its lightweight properties. It is important to consult with a professional to determine the best material for your specific pipe bending needs.

Tube bending calculations
The factors to consider in tube bending calculations include the material properties of the tube, the radius of the bend, the wall thickness of the tube, and the degree of bend required.
The material of the tube can have a significant impact on tube bending calculations. The elasticity, strength, and ductility of the material can all affect the amount of force required to bend the tube and the degree of bending that can be achieved without causing cracking or deformation.
For example, a more ductile material such as aluminum may require less force to bend than a less ductile material such as stainless steel. Additionally, the thickness of the tube walls and the diameter of the tube can also impact the bending calculations.
Therefore, it is important to take into consideration the specific material properties when performing tube bending calculations to ensure accurate and safe results.
Abaqus Bending Pipe Plugin
During the development of a product, it is important to know the feasibility of the product before the manufacturing stage. One of the activities covered by the metal forming process is the bending pipe process and it is critical, to save costs and time, a feasible design.
The bending pipe plugin for Abaqus is intended to cover this necessity, allowing the designer to assess the bending process easily and quickly.

The bending pipe plugin is completely parametrized for the circular sections and does not need expert knowledge about the bending process. The user to confirm the material and dimensions of the tube and tools. The plugin is divided into different steps, which help the user through model performance. The bending pipe plugin also implemented different methods of bending such as:
Classical Bending
Also named Rotary Draw Bending. It is the most typical bending method when you need to keep the original section of the pipe and reach complex geometries.

Compression Bending
It is similar to Classical Bending, but it is more simple and is not capable of making complex geometries.
Roll Bending
This method has roller components, which are continuously moving. It is suitable for long-bent radii.
Press Bending
The tooling in this method has the final shape of the pipe and is formed by press forces, like in the stamping process.
Stretch Bending
In this method, the pipe is subjected to tensile force, and the bent is done by rotating the pipe ends on a Die tool.
One Step
currently, this option only creates both meshes undeformed and deformed, which could be used with inverse analysis capability in Abaqus 2019 or higher.
