The Study of Bolt Severance by a Bolt Cutter - Webinar

Severing a bolt is a dynamic and complicated event; the severance mechanism has been difficult to understand because the entire process takes less than one millisecond. Bolt severance includes both penetration of the bolt by the downward-accelerating knife, and fragmentation of the bolt on the wedge-shaped anvil underneath.

To better understand the bolt severance mechanism for reliable bolt cutter design, engineers at Pacific Scientific Energetic Materials Company used ANSYS Autodyn explicit dynamics software in Lagrangian mode. In this webinar, you will learn that fast pressure rise and high peak pressure are the most critical parameters for bolt severance. You will also take away an understanding of the five-step mechanism for bolt severance that the engineers extracted from post-simulation analysis.
