Design, Refine and Manufacture Advanced Fastening Systems – Virtually

Fastener and precision cold forming manufacturers are using DEFORM to simulate mechanical joining processes, such as riveting, bolting, and clinching, to accelerate product development and avoid the cost and time of physical testing. This includes the modelling of annealing operations designed to locally soften material and influence its deformation behaviour. DEFORM can predict the shape of each component, installation load, torque, joint strength and tool stress.

Furthermore, DEFORM’s renowned process modelling capabilities are also applied to the manufacture of fastener products, including cold and warm forming operations. Progression designs can be optimized through virtual prototyping to reduce number of stages, decrease forming load requirements, minimize die stresses and increase tool life.

Applications

While simulation of multiple bodies undergoing small deflections is possible with general purpose FEA codes, large plastic deformation of multiple components requires very powerful analysis capabilities with sophisticated contact algorithms for accurate results.

DEFORM is consequently the preferred simulation solution for fastener companies across the world. In addition, its extensive thermo-mechanical modelling capabilities mean the software is increasingly used to investigate welding and other challenging processes too.
