Impact Analysis of Additive Manufactured Lattice Structures

We are pleased to announced a year-long contract award from the US Army Natick Soldier Systems Center (NSSC) to continue the investigation of additive manufactured materials for improved blunt force protection in helmet systems.  Our role is to work with Natick’s engineering team to simulate the impact behavior of additive manufactured 3D lattice systems.  In prior work  (see our Case Study: Impact Analysis of Additive Manufactured Lattice Structures) we discovered that getting the material characterization correct was not easy.  In this new work, we’ll revisit that whole process and look into manufacturing variability of the additive materials from bulk samples down to thin noodle-like structures that are necessary to for the 3D lattice structures of the foam replacement pads.

Next Generation CFD

The way we think of the design process is changing. Join us as we host an online seminar covering where CFD & engineering design trends are headed. We'll help you explore STAR-CCM+, the integrated multiphysics solution for CFD engineers.

Attendees will see how to evaluate the design space though the use of parametric CFD studies and design exploration. The presentation consists of three parts: an overview of the design challenge, setting up of the design space, and an evaluation of the parametric results.

Discover how your company can innovate to the next generation.
