By utilizing CAE (Computer Aided Engineering) in Crimping, you can predict the deformation behaviors of several materials, and clamping force after the process, thereby preventing possible defects. In this article, we will focus on “Crimping” and introduce benefits of the CAE analysis, and case studies.

WHAT IS CRIMPING?
Crimping is a method of joining two pieces of sheet-shaped parts by deforming.
There are two types of methods in Crimping; one is a fastening method that involves inserting a rivet into the pre-drilled hole of two sheet materials, and deforming the rivet by pressing; the other is a joining method that fasten interlocking-shaped materials by bending and pressing them together to create a tight bond between two metals.
The advantages of Crimping are that it enables you speedy processing, is easy to automate, and produce stable hardness, and that is suitable for assembling precision sheet metal components.
The disadvantages are that it costs and takes time because for example, riveting requires components other than the work pieces, and that it is difficult to break the components down after the process.
Common Crimping methods are as follows:
- Seaming
- Hemming
- Corner Crimping/Clinching
- Riveting
BENEFITS OF CAE ANALYSIS FOR CRIMPING
CAE analysis for Crimping enables you to predict the deformation behaviors of several materials and clamping force after crimping. It allows you to prevent possible defects through the processes ahead by setting the proper thickness of the materials, clearance, and crimp. So, you can reduce the production costs of components.

CASE STUDIES (Click on the image to visit the 3D animation page)
Here are case studies of Crimping, such as bolt crimping and riveting, using several deformable tools.
Several forming conditions, such as timing for actions of anvils, velocity, and temperature, make differences in forming shapes.
