CAETestBench Validations Add Confidence to Simulation Outcomes

CAETestBench is a mid-stage validation procedure in which a standardized physical part is created and tested under a rigid protocol that can be accurately reproduced in simulation. Using techniques such as digital image correlation (DIC), it is possible to probe the accuracy of the simulation prior to use in real-life situations. The test cases range from simple tensile modes to more complex multi-axial modes, impact and failure. CAETestBench validations are available for plastics and additively manufactured metals; validations for rubbers are currently under development (see A Mechanism for the Validation of Hyperelastic Materials in ANSYS).

Latest Matereality® Release Delivers New Capabilities for Enterprise Materials Workflows

New Importer module in Matereality V10.1Matereality Version 10.1 is in the final stages of testing before being made available on the Matereality Cloud and for Enterprise MDS installations. New capabilities include tools for importing large amounts of legacy data into your libraries, and additional supported CAE Modeler formats for LS-DYNA.

Updated Import capabilities (Enterprise licenses only)

The Importer module can be used to import data into Matereality by copy and paste from Excel. Use the Importer to:
  • Define and classify multiple Materials
  • Create multiple material Specifications
  • Load single point property data and equation coefficients for multiple Materials
  • Enter property limits for multiple material Specifications

Templates for loading property data and specification property limits are user-created with the MIRO Designer app.

New supported CAE formats (Pro licenses only)

The CAE Modeler now supports creation of the following material models for LS-DYNA using the updated framework:
  • MAT_019
  • MAT_024 LCSS
  • MAT_024 LCSR
  • MAT_089 LCSR

Select these models under LS-DYNA in the CAE Modeler app.

Matereality Webinar: CAE Modeler for Altair RADIOSS

December 1, 2016
10:00 AM EST

REGISTER NOW

Learn how to use Matereality’s Workgroup Material DatabasePro on Altair’s HyperWorks Platform to convert raw data in your database into properly formatted CAE Material files for use in RADIOSS, including the use of a validation step to gauge the solver accuracy:

  • Locate property data in your Workgroup database
  • Add missing material property data and CAE Material files
  • Create CAE material files for your CAE software from raw data in your database using the CAE Modeler for RADIOSS
  • Export your CAE Material files for your project to a HyperWorks Collaboration Tools master material library
  • Gauge the accuracy of your simulation using a mid-stage validation in HyperWorks

The webinar will be presented by Adam Beckwith, Matereality software product manager, and Megan Lobdell, DatapointLabs engineer.

Knowmats Site Features Recent Technical Publications on "Materials in Simulation"

DatapointLabs Technical Center for Materials presented several well-received conference papers this Fall. Presentations focused generally on the topic of “Validate Before You Simulate,” evaluating factors that can affect simulation accuracy. If you missed our presentations at these conferences, find them at any time on Knowmats.com, a curated repository of information related to materials and simulation:

New Book: Determination and Use of Material Properties for Finite Element Analysis

DatapointLabs founder and CEO, Hubert Lobo, and laboratory director, Brian Croop, have written a book describing the state of the art in material testing for CAE. This book informs simulation users of the manner and methodologies by which materials are tested in order to calibrate material models currently implemented in various FEA programs. It incorporates extensions beyond basic material models to address currently active areas, including explicit simulation.

Find a review of this book on Knowmats.com. It is available for purchase directly from NAFEMS.org.
