"Selecting Material Models for the Simulation of Foams
in LS-DYNA"
Brian Croop and Hubert Lobo
In our current work, we seek to lay down a framework to help us understand the different behavioral classes of foams. Following a methodology that we previously applied to plastics, we propose the right LS-DYNA material models that best capture these behaviors.more

"Material Modeling of Soft Material for Non-linear NVH
Applications in Abaqus"
Hubert Lobo
Abaqus’ non-linear NVH capability permits the capture of material behavior of rubber seals and bushings, plastic parts and foam inserts which have a significant influence on the simulation. In this presentation, we discuss material calibration procedures for this application. more

"Characterization of Damage in Hyperelastic Materials Using Standard Test Methods"
*Arun Nair, **Hubert Lobo, *Anita Bestelmeyer
*Becton Dickinson & Company and **DatapointLabs
Well established physical test methods and computational procedures exist for the characterization of the material behavior in tension, compression, shear volumetric response, tear strength etc. However, effective modeling of the fracture behavior of hyperelastic materials using finite element techniques is very challenging. In this paper, we make an attempt to demonstrate the use of such standard test methods and the applicability of such test data for performing finite element analyses of complex nonlinear problems using Abaqus.

"A Robust Method to Calibrate Crash Materials"
Hubert Lobo
High strain rate material modeling for use in crash and drop testing has been plagued by a number of problems. These include poor quality data, material models unsuited to polymer behavior, and unclear material model calibration guidelines, to name just a few. This has rendered the modeling of polymers to be a risky proposition with a highly variable success rate. In previous work,
we tackled each of the above problems individually. more
