Use of ARAS 360 to Facilitate Rapid Development of Articulated Total Body Biomechanical Physics Simulations
The development of 3-dimensional environments to be used within a biomechanical physics simulation framework, such as Articulated Total Body, can be laborious and time intensive. This brief article demonstrates how the ARAS 360 software package can aid the user by speeding up development time.

Illustrations of Equivalent Methods to Reproduce Vehicle and Occupant Dynamics as a Pedagogical Tool
When explaining to a lay audience the magnitude of forces or accelerations imparted to vehicles or experienced by vehicle occupants during a motor vehicle collision, it is often helpful to recast the critical results in terms of other physical systems or impact configurations which will reproduce the equivalent dynamics of the subject accident to serve as a conceptual aid for the audience. In this article, we present the basis for such equivalents and explicitly demonstrate, using two physics simulation software packages, that such equivalents are based on nothing more than the application of the laws of physics.

The Effect of Inflated Backrest Stiffness on Shearing Loads Estimated with Articulated Total Body
In the construction of simulations of rear-end vehicle impacts, the Articulated Total Body (ATB) software package can be a useful tool. In this article we discuss the effect of using artificially inflated values for seat-backrest stiffness in ATB simulations. We will also present methods for quickly assessing the quality of simulation results. In this connection, we will discuss the perils of using the default contact-force models that are included in ATB package releases.
