Fracture simulation of cold roll forming process for aluminum 7075-T6 automotive bumper beam using GISSMO damage model

Simulating the Complete Forming Sequence for a Roll Formed Automotive Bumper Beam Authors:

As part of the development of a new automotive bumper beam, a complete simulation of the entire forming process was carried out using LS-DYNA. The material for the beam was an ultra high strength steel presenting many challenges for the forming process. The sequence of forming operations was roll-forming (including forming a sweep in the initially straight roll-formed section), local annealing,...

Stress Analysis and Energy Estimation in Cold-Roll Forming Process

In this article, stress analysis and energy estimation during cold-roll forming of symmetrical channel sections have been discussed. Geometry of sheet strip is pre-estimated by a shape function. Then longitudinal, transversal and shear strains have been calculated. Using both the Levy-Mises and the Prandtl Reuss equations, and also considering the Bauschinger effect, stress distributions have b...

EXPERIMENTAL POLYMERIC NANOCOMPOSITE MATERIAL SELECTION FOR AUTOMOTIVE BUMPER BEAM USING MULTI-CRITERIA DECISION MAKING METHODS

Material selection is a main purpose in design process and plays an important role in desired performance of the products for diverse engineering applications. In order to solve material selection problem, multi criteria decision making (MCDM) methods can be used as an applicable tool. Bumper beam is one of the most important components of bumper system in absorbing energy. Therefore, selecting...
