Crashworthiness of Magnesium Sheet Structures [PDF]

Materials Science Forum, 2013
A hollow rectangular profile, as an example of a typical structural component made of magnesium alloy sheets has been built, tested and evaluated in order to assess its behaviour during axial crushing. The profiles were joined from plane sheets of AZ31 and ZE10, respectively, by laser beam welding and were then tested in compression.

Prediction of Vehicle Crashworthiness Parameters Using Piecewise Lumped Parameters and Finite Element Models

Designs, 2018
Estimating the vehicle crashworthiness experimentally is expensive and time-consuming. For these reasons, different modelling approaches are utilised to predict the vehicle behaviour and reduce the need for full-scale crash testing. The earlier numerical

Crashworthiness of Electric Vehicles [PDF]

World Electric Vehicle Journal, 2010
This paper describes the crashworthiness of electric vehicles when the vehicle has alterations from a gasoline engine to an electric motor. The crashworthiness is dependent on the crushable length of the frame and the center of gravity. It is presumed that the transfer of the center of gravity has the disadvantage in a crash.
